Android: how can I rotate image and set it filling fragment?

I have a fragment that displays some images on 30% of the screen. In case when image.height is bigger than image.width, I wanted to rotate the image 90 degrees. However, after that operation, the image does not fully fill the fragment - "new" width after rotation matches previous height, so the image occupies only some part in the middle of the fragment. How can I make it a matching fragment? What I'm doing wrong or missing?
This is how it looks like without rotation:
This is after rotation:
And that's what I want to have:
Here is the code:
#Override
public void onViewCreated(#NonNull View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
setImageFittedToDisplay(view);
}
public void setImageFittedToDisplay(View view) {
int height = getDisplayMetrics().heightPixels;
ViewGroup.LayoutParams params = view.getLayoutParams();
params.height = ((Double) (height * 0.3)).intValue();
view.setLayoutParams(params);
ImageView image = view.findViewById(R.id.picture);
image.setDrawingCacheEnabled(true);
int w = image.getDrawable().getIntrinsicWidth();
int h = image.getDrawable().getIntrinsicHeight();
if(h > w) {
image.setRotation(90f);
}
ViewGroup.LayoutParams imageParams = image.getLayoutParams();
imageParams.height = ActionBar.LayoutParams.WRAP_CONTENT;
imageParams.width = ActionBar.LayoutParams.WRAP_CONTENT;
image.setLayoutParams(imageParams);
}
and here is .xml of the fragment:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

android:id="#+id/APOD_layout"

TextView breaks my word by letters

My requirements: create "incoming bubble" with width by content and max width 90%.
I have this markup:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1.0"
tools:background="#color/white_smoke">
<LinearLayout
android:id="#+id/flBubble"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:background="#drawable/bubble_in"
android:layout_weight="0.9">
<ImageView
android:id="#+id/ivSay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="?android:attr/selectableItemBackground"
android:contentDescription="#string/default_content_description"
android:padding="8dp"
android:src="#drawable/ic_play_circle_outline_black_24dp"
android:tint="#color/primary"/>
<TextView
android:id="#+id/tvValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:padding="8dp"
android:textColor="#color/black"
android:textSize="16sp"
tools:text="I would like to go to an Italian restaurant"/>
</LinearLayout>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0.1"/>
</LinearLayout>
Sometimes I get the following result:
But I expect the following result (it's falsely encouraging screenshot from Android Studio preview):
How can I prevent breaking word restaraunt by letters?
UPDATE
Although I use minSdk=15 I tried to use breakStrategy and I haven't get expected result.
android:breakStrategy="simple":
android:breakStrategy="balanced":
I found a related question: Force next word to a new line if the word is too long for the textview, but I didn't undestand how can I get maximum available width for TextView with layout_width="wrap_content?
It would be great if I could override the TextView.setText and place line breaks there if needed.

OMG, there were in my string!
value.replaceAll("\\s", " ");
Thank you all!

Use MaxWidth property for textview or else you should provide width for textview
<com.custom.views.CustomTextView
android:id="#+id/txt_send_chat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:maxWidth="250dp"
android:textColor="#color/color_chat_sender"
android:textSize="16sp"
app:font_name="#string/font_roboto_regular" />

You can use webview to achieve this behavior.
In webview you can use css to adjust text.
Take a look at this answer
Update
You can calculate width of string and add \n to string where is string needs to split
Rect bounds = new Rect();
Paint textPaint = textView.getPaint();
textPaint.getTextBounds(text, 0, text.length(), bounds);
int height = bounds.height();
int width = bounds.width();
Results is in pixels, so just check width of your view or screen and split the string.
UPDAE2: Example Code
I just wrote an example with simple layout in activity onCreate you can implement it in adapter or whatever works for you.
TextView textView = (TextView) findViewById(R.id.txt); //textview with empty text
Rect bounds = new Rect();
Paint textPaint = textView.getPaint();
String text = "some long text here.....";// text data to work on
textPaint.getTextBounds(text, 0, text.length(), bounds);
int textWidth = bounds.width();// get text width in pixel
int marginPadding = 100;// we have some padding and margin from xml layouts
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int rootWidth = displayMetrics.widthPixels-marginPadding;// maximum width on screan
if (textWidth > rootWidth) { // check if need to split the string.
int lineMax = (text.length() * rootWidth) / textWidth; // maximum Characters for each line
String result = text.replaceAll("(.{" + String.valueOf(lineMax) + "})", "$1\n"); // regex to replace each group(lineMax) of Chars with group of char + new line
textView.setText(result);
} else
textView.setText(text);
UPDATE#3: Fixed code for Listview
onCreate
ArrayList<String> data = new ArrayList<>();
data.add("000");
data.add("aaaaaaaaaaa");
data.add("aaaaaaaaaaa bbbbbbbbbbbb");
data.add("aaaaaaaaaaa bbbbbbbbbbbb cccccccccccccccc");
data.add("aaaaaaaaaaa bbbbbbbbbbbb cccccccccccccccc ddddddddddddd");
data.add("aaaaaaaaaaa bbbbbbbbbbbb cccccccccccccccc ddddddddddddd eeeeeeeeeeeee");

You can try with
Autosizing TextViews
The Support Library 26.0 provides full support to the autosizing TextView feature on devices running Android versions prior to Android 8.0 (API level 26). The library provides support to Android 4.0 (API level 14) and higher. The android.support.v4.widget package contains the TextViewCompat class to access features in a backward-compatible fashion
For Example:
<TextView
android:layout_width="match_parent"
android:layout_height="200dp"
android:autoSizeTextType="uniform" />
For more details Guidelines go HERE
Their is Library too HERE

Try this
private String getWidthFitString(String input) {
Paint paint = text.getPaint();
// you can define max width by your self
int maxWidth = getContentMaxWidth();
float width = paint.measureText(input);
if (width > maxWidth) {
List<String> words = Arrays.asList(input.split("\\s"));
int breakLinePosition = 0;
String toBreakLineText;
List<String> toBreakLineWords = new ArrayList<>();
while (breakLinePosition < words.size()) {
toBreakLineWords.add(words.get(breakLinePosition));
toBreakLineText = TextUtils.join(" ", toBreakLineWords);
float currentWidth = paint.measureText(toBreakLineText);
if (currentWidth > maxWidth) {
break;
}
breakLinePosition ++;
}
if (breakLinePosition > 1) {
toBreakLineWords.remove(toBreakLineWords.size() - 1);
toBreakLineText = TextUtils.join(" ", toBreakLineWords);
List<String> fromBreakLineWords = new ArrayList<>();
for (int i = breakLinePosition; i < words.size(); i++) {
fromBreakLineWords.add(words.get(i));
}
return toBreakLineText + "\n" + getWidthFitString(TextUtils.join(" ", fromBreakLineWords));
} else {
return input;
}
}
return input;
}

For those whose string has non-breaking space character may try the following:
value.replace("\u00A0", " ")
Hope this might help

Change your TextView to EditText and put this 2 lines. it should help you
android:inputType="textMultiLine"
android:enabled="false"
This will place you text properly and later on you can give a edit feature in your application if you need.

Out of memory Exception on Listview with images and text

My App has run out of memory due to a ListView with an ImageView and 2 TextView's inside. The images are big and I shrink them down to 56x56dp in single_row.xml for the ListView, but they are also used in larger sizes on other screens.
The MainActivity calls the single_row into the listview and inflates it. Then the single row is duplicated with individual content for each row. Each row has an image and 2 textviews. I know there's a way to use bitmap but I'm unsure how to implement it in the code.
Here is the main activity.java code
#Override public View getView(int i, View convertView, ViewGroup viewGroup) {
View row=convertView;
if(row==null){
LayoutInflater inflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row=inflater.inflate(R.layout.single_row, viewGroup,false);
}
TextView title = (TextView) row.findViewById(R.id.textView);
TextView description = (TextView)row.findViewById(R.id.textView2);
ImageView image = (ImageView)row.findViewById(R.id.imageView);
SingleRow temp=list.get(i);
title.setText(temp.title);
description.setText(temp.description);
image.setImageResource(temp.image);
return row;
}
here is the singlerow.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/imageView"
android:layout_width="56dp"
android:layout_height="56dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_margin="10dp"
android:src="#drawable/placeholder1" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/imageView"
android:layout_toRightOf="#+id/imageView"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imageView"
android:layout_alignLeft="#+id/textView"
android:layout_alignParentRight="true"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>`
Any solution would be helpful. I'm unsure how to implement it in this specific structure.

As Karakuri said, restricting the ImageView size to 56dpx56dp doesn't mean that the entire bitmap is not loaded. First load the bitmap from the file (or resource), and shrink it. Use
//For resource
image.setImageBitmap(decodeSampledBitmapFromResource("android.resource://com.my.package/drawable/image_name"));
//For file
image.setImageBitmap(decodeSampledBitmapFromResource(filepath));
public static int calculateInSampleSize(BitmapFactory.Options options,
int reqWidth, int reqHeight) {
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 2;
if (height >= reqHeight || width >= reqWidth) {
inSampleSize *= 2;
}
return inSampleSize;
}
public static Bitmap decodeSampledBitmapFromResource(String file,
int reqWidth, int reqHeight) {
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(file, options);
options.inSampleSize = calculateInSampleSize(options, reqWidth,
reqHeight);
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(file, options);
}

How to set a maximum height with wrap content in android?

In android, how can you create a scroll view that's got a max height, and wrap contents, basically it wraps the content vertically, but has a maximum height?
I tried
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:maxHeight="200dp"
android:layout_alignParentBottom="true" >
<LinearLayout
android:id="#+id/maincontainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
But this isn't working?

you can add this to any view (override onMeasure in a class inherited from a view)
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (maxHeight > 0){
int hSize = MeasureSpec.getSize(heightMeasureSpec);
int hMode = MeasureSpec.getMode(heightMeasureSpec);
switch (hMode){
case MeasureSpec.AT_MOST:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Math.min(hSize, maxHeight), MeasureSpec.AT_MOST);
break;
case MeasureSpec.UNSPECIFIED:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(maxHeight, MeasureSpec.AT_MOST);
break;
case MeasureSpec.EXACTLY:
heightMeasureSpec = MeasureSpec.makeMeasureSpec(Math.min(hSize, maxHeight), MeasureSpec.EXACTLY);
break;
}
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

I've extended ScrollView and added code to implement this feature:
https://gist.github.com/JMPergar/439aaa3249fa184c7c0c
I hope that be useful.

You can do it programmatically.
private static class OnViewGlobalLayoutListener implements ViewTreeObserver.OnGlobalLayoutListener {
private final static int maxHeight = 130;
private View view;
public OnViewGlobalLayoutListener(View view) {
this.view = view;
}
#Override
public void onGlobalLayout() {
if (view.getHeight() > maxHeight)
view.getLayoutParams().height = maxHeight;
}
}
And add listener to the view:
view.getViewTreeObserver()
.addOnGlobalLayoutListener(new OnViewGlobalLayoutListener(view));
Listener will call method onGlobalLayout(), when view height will be changed.

It can be done by wrapping the view into ConstraintLayout and using layout_constraintHeight_max attribute.
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="200dp">
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHeight_max="wrap"
app:layout_constraintVertical_bias="0">
...
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
In the example above, the parent ConstraintLayout height is limited to 200dp, and the child ScrollView height wraps the content till it's less than 200dp. Note that app:layout_constraintVertical_bias="0" aligns the child ScrollView at the top of the parent, otherwise it will be centered.

for set scrollview height you must use 2 linerlayout inside together and then set scrool view as them child then set middle linerlayout layout:height for limit scrollview height.

1.) Create a class to handle setting maximum height to what is passed by the user:
public class OnViewGlobalLayoutListener implements ViewTreeObserver.OnGlobalLayoutListener {
private Context context;
private int maxHeight;
private View view;
public OnViewGlobalLayoutListener(View view, int maxHeight, Context context) {
this.context = context;
this.view = view;
this.maxHeight = dpToPx(maxHeight);
}
#Override
public void onGlobalLayout() {
if (view.getHeight() > maxHeight) {
ViewGroup.LayoutParams params = view.getLayoutParams();
params.height = maxHeight;
view.setLayoutParams(params);
}
}
public int pxToDp(int px) {
DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
int dp = Math.round(px / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
return dp;
}
public int dpToPx(int dp) {
DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
int px = Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
return px;
}
}
2.) Attach this to the view and pass the maximum height in DP:
messageBody.getViewTreeObserver()
.addOnGlobalLayoutListener(
new OnViewGlobalLayoutListener(messageBody, 256, context)
);
Thanks to #harmashalex for the inspiration. I made modifications to as setting the layout params didn't work by #harma's code. Also, dp-to-px conversion is necessary to offload wondering about it.

Here you can set height of your Scrollview like this -:
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_alignParentBottom="true" >
<LinearLayout
android:id="#+id/maincontainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>

ImageView doesn't wrap content in RelativeLayout

I have a TableLayout with 6 childs/entrys. These childs are a custom RelativeLayout. In each RelativeLayout is a big TextView in the middle and an ImageView and small TextView at the bottom.
The ImageView should be as tall as the TextView next to it. That's why I set the attribute ALIGN_TOP and ALIGN_BOTTOM to the TextView (you can see it in code below). This works very well and both - ImageView and TextView - have the same height now. But the problem is, that the left and right side of the ImageView don't "wrap content" anymore (as you can see on the screenshot).
Is there a way to fit the left and right side to the image and remove the "padding"?
Here is my code:
view_display_component.xml
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android" >
<TextView
android:id="#+id/tvDisplayBig"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_weight="1"
android:gravity="center"
android:textColor="#color/white"
android:textSize="#dimen/font_size_extra_large" />
<ImageView
android:id="#+id/imageViewDisplayIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_below="#id/tvDisplayBig"
android:layout_gravity="bottom"
android:adjustViewBounds="true"
android:baselineAlignBottom="true"
android:scaleType="fitCenter"
android:src="#drawable/stopwatch_64"
android:visibility="visible" />
<TextView
android:id="#+id/tvDisplaySmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="bottom"
android:includeFontPadding="false"
android:textColor="#color/white"
android:textSize="#dimen/font_size_small" />
</merge>
class DisplayComponent which extends RelativLayout
public DisplayComponent(Context context) {
super(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.view_display_component, this, true);
tvDisplay = (TextView) getChildAt(0);
icon = (ImageView) getChildAt(1);
tvName = (TextView) getChildAt(2);
setupAlign();
}
private void setupAlign() {
if(index % 2 == 0) { // LEFT SIDE
// same as "RIGHT SIDE"
} else { // RIGHT SIDE
RelativeLayout.LayoutParams paramsIcon = (RelativeLayout.LayoutParams) icon.getLayoutParams();
paramsIcon.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
paramsIcon.addRule(RelativeLayout.ALIGN_TOP, tvName.getId());
paramsIcon.addRule(RelativeLayout.ALIGN_BOTTOM, tvName.getId());
icon.setLayoutParams(paramsIcon);
RelativeLayout.LayoutParams paramsTvName = (RelativeLayout.LayoutParams) tvName.getLayoutParams();
paramsTvName.addRule(RelativeLayout.RIGHT_OF, icon.getId());
tvName.setLayoutParams(paramsTvName);
tvName.setBackgroundColor(Color.BLUE); // only for testing
icon.setBackgroundColor(Color.YELLOW);
}

I found an (ugly) solution. Because my icon is square, I created a custom ImageView and overrode the onSizeChanged() method like this:
public class IconImageView extends ImageView {
public IconImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
if(h != oldh && h > 0)
getLayoutParams().width = h; // same width as height
}
}
But this works only if the image is square. That's why I am still searching for a better solution. Maybe some layout solution with a better setting of alignment.
Best regards!
