So im using this awesome Cards library (CardsUI) and trying to figure out how to insert my own text into these views grammatically. Im my main activity im parsing JSON data, now i want to use data from the JSON and insert the text into the Cards. Here is some code i have so far.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hello_enlighten);
// the id title is referencing the title in my card layout below
system_id = (TextView) findViewById(R.id.title);
system_name = (TextView) findViewById(R.id.system_name);
CardUI mCardView = (CardUI) findViewById(R.id.cardUI1);
mCardView.setSwipeable(false);
// add AndroidViews Cards
mCardView.addCard(new MyCard("Get the CardsUI view"));
mCardView.addCardToLastStack(new MyCard("for Android at"));
MyCard androidViewsCard = new MyCard("www.androidviews.net");
mCardView.addCardToLastStack(androidViewsCard);
// draw cards
mCardView.refresh();
// Here is my JSON Parsing activity.
new ProgressTask(WelcomeYou.this).execute();
}
My Card Layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="16dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:paddingLeft="8dp"
android:paddingRight="8dp" >
<TextView
android:id="#+id/title"
style="#style/CardTitle"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="title" />
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginTop="4dp"
android:background="#color/stroke" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/selectable_background_cardbank"
android:gravity="center_vertical"
android:padding="4dp" >
<TextView
android:id="#+id/description"
style="#style/CardText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:ellipsize="end"
android:maxLines="4"
android:text="description" />
</LinearLayout>
</LinearLayout>
Im simply trying to put text into the here mCardView.addCard(new MyCard("PUT JSON STRING HERE"));
I know this question was posted a while ago, but I'm just now using the CardUI and I've got it to work. I don't know what R.id.activity_hello_enlighten contains, but if you look at the example provided with their source, the layout from your activity should be using a CardUI component.
Code from the example layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.fima.cardsui.views.CardUI
android:id="#+id/cardsview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Otherwise there's nothing actually doing your card rendering to the screen.
Once you do this, get a pointer to the CardUI referenced by your layout (in the example code it's called cardsview) with the following code:
mCardView = (CardUI) findViewById(R.id.cardsview);
After that, it's as simple as adding a new card like this:
mCardView.addCardToLastStack(new MyCard("Your card's text!"));

After implementing a title and subtitle for my toolbar, the wrong font size is used for some reason. What needs to be done in order to fix this?
Java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar customToolbar = (Toolbar)findViewById(R.id.toolbarC);
customToolbar.setBackgroundColor(Color.parseColor("#E21836"));
TextView mTitle = (TextView) this.findViewById(R.id.toolbar_title);
mTitle.setText("Hello World");
mTitle.setSingleLine(true);
TextView mSubtitle = (TextView) this.findViewById(R.id.toolbar_subtitle);
mSubtitle.setText("Hello World");
mSubtitle.setSingleLine(true);
}
}
toolbarC.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbarC"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"

<LinearLayout
android:id="#+id/header_text_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="wrap_content"

add textSize to each textViews. Try like this
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
style="#style/TextAppearance.AppCompat.Widget.ActionBar.Subtitle"/>
</LinearLayout>
add this line, probably it's using app_name as title
getSupportActionBar().setDisplayShowTitleEnabled(false);
and try using dp instead of sp
Found the problem and have solved it. There was a hidden duplicate of the toolbar text views within my project and the duplicate title & subtitle were what was shown to me when deploying my app.
Increase Toolbar's Height to ?actionBarSize
I'm working on a gallery type app. The issue that I have at the moment is trying to fetch the typed text within an EditText. The error that I am getting is a casting exception because the code fetches the EditText block from the layout as a TextView block. This only occurs after I swipe, which causes the some of the LinearLayouts imbeded in the second GridLayout to be removed.
The LinearLayouts are put in at runtime into the Gridlayout (with the id product_details), the amount Layouts is calculated according to which picture is pressed on.
This part of the code fetches the current LinearLayouts that are imbeded in the GridLayout:
for (int i = 0; i<codes.size(); i++) {
//Sets the different elements to te correct texts
ViewGroup linearLayout = (ViewGroup) gridLayout.getChildAt(i);
TextView textCode = (TextView) linearLayout.getChildAt(0);
TextView textPrice = (TextView) linearLayout.getChildAt(1);
EditText editTextQ = (EditText) linearLayout.getChildAt(2);
EditText editTextC = (EditText) linearLayout.getChildAt(4);
commentsAddList.add(editTextC.getText().toString());
quantityAddList.add(editTextQ.getText().toString());
priceAddList.add(textPrice.getText().toString().substring(1));
codeAddList.add(textCode.getText().toString());
productModelAddList.add(new ProductModel());
productModelAddList.get(i).setCode(codeAddList.get(i));
if(!quantityAddList.get(i).equals("")) {
productModelAddList.get(i).setQuantity(Integer.parseInt(quantityAddList.get(i)));
}else{
productModelAddList.get(i).setQuantity(0);
}
productModelAddList.get(i).setComment(commentsAddList.get(i));
if(!priceAddList.get(i).equals("")) {
productModelAddList.get(i).setPrice(Double.parseDouble(priceAddList.get(i)));
}else{
productModelAddList.get(i).setPrice(0);
}
mRequestPermissions();
adaptToText.addToList(productModelAddList.get(i));
}
The main picture xml Layout:
<?xml version="1.0" encoding="utf-8"?>

I'm not sure where the casting exception is caused or why exactly it happened. If anyone is able to help, I would appreciate it a lot! Thanks in advance!
Instead of getting the view by position getting it by id would be easier.
EditText editTextQ = (EditText) linearLayout.getChildAt(2);
EditText editTextC = (EditText) linearLayout.getChildAt(4);
Try this instead:
EditText editTextQ = (EditText) linearLayout.findViewById(R.id.editText1);
EditText editTextC = (EditText) linearLayout.findViewById(R.id.editTextComments);
This will be better because if change the xml, it could change view positions, and find views by id you wouldn't need to change the code.
I need a TextView which scrolls automatically vertically. This is my layout code:
activity_info.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/iView"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerHorizontal="true"
android:contentDescription="#string/info"
android:src="#mipmap/infoImage" />
<TextView
android:id="#+id/tView"
android:layout_below="#+id/iView"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_centerHorizontal="true"
android:maxLines="500"
android:scrollbars="vertical" />
<RelativeLayout
android:layout_below="#+id/tView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center">
<Button
android:id="#+id/buttonYes"
android:layout_width="100dp"
android:layout_height="50dp"
android:text="YES" />
<Button
android:id="#+id/buttonNo"
android:layout_toEndOf="#id/buttonYes"
android:layout_width="100dp"
android:layout_height="50dp"
android:text="NO" />
</RelativeLayout>
</RelativeLayout>
I read that I have to input this line:
tView.setMovementMethod(new ScrollingMovementMethod())
into my onCreate method in my activity:
InfoActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_info);
TextView tView = (TextView) findViewById(R.id.tView);
tView.setMovementMethod(new ScrollingMovementMethod());
}
If I do that, the TextView does not scroll automatically, if some new input (text) is inserted into the View. I know there are some other questions concerning the problem. But I've tried most of them.
How can I solve this problem?
Try to set the textView to android:gravity="bottom"
and use textView.append("\n"+"New Input Text."); for new input text;
You are almost there. Just add a few more things to achieve this,
First of all add those properties in your TextView
android:maxLines = "AN_INTEGER"
android:scrollbars = "vertical"
android:gravity="bottom"
Secondly as usual use,
tView.setMovementMethod(new ScrollingMovementMethod());
This should solve your problem.
I would suggest wrapping your TextView in a ScrollView
<ScrollView
android:id="#+id/sView"
android:layout_below="#+id/iView"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_centerHorizontal="true" >
<TextView
android:id="#+id/tView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:maxLines="500"
android:scrollbars="vertical"
android:gravity="bottom" />
</ScrollView>
You can append new text by doing
public void appendAndScrollDown(String someText) {
tView.append("\n" + someText);
sView.fullScroll(View.FOCUS_DOWN);
}
I've created what I want in xml but I need to do it programatically and I can't get it to work. It's a table layout with one row. In that row there is two more table layouts. The first of which has one row containing a picture and the second table layout has two rows containing two textviews and a picture. Is there some kind of xml to java converter? I've tried to write the code now for a couple of hours and can't get the layouts to work. I'd post a picture but I need 10 rep points first. The whole xml file is in a linear layout if it helps.

This is the new code I'm trying to use based on Nathan Walter's advice. However, It'll set the first set text but the rest are just the default value. Although the layout looks right. How can I set the textfields for each individual view when the method is called.
public void Display(String name, String ctroom) {
ViewGroup parent = (ViewGroup) findViewById(R.id.container);
view = LayoutInflater.from(this).inflate(R.layout.tablebutton, null);
parent.addView(view);
TextView jn = (TextView) findViewById(R.id.JudgenameCourts);
jn.setText(name);
TextView ct = (TextView) findViewById(R.id.Courtroomnew);
ct.setText(ctroom);
view = LayoutInflater.from(this).inflate(R.layout.tablebutton, null);
parent.addView(view);
jn.setText("Name1");
ct.setText("Courtroom1");
}
I think the code you want looks something like this. Let me know if it makes sense.
// Create an array of things to create views from.
// You will probably be getting your array from somewhere else
YourObjectHere[] things = new YourObjectHere[2];
things[0] = new YourObjectHere();
things[1] = new YourObjectHere();
// Get a reference to a LinearLayout to hold your views
LinearLayout list = (LinearLayout) findViewById(R.id.list);
// Loop through your list of objects
for(int i = 0; i < things.length; i++) {
// Inflate an instance of your layout
View listItem = getLayoutInflater().inflate(R.layout.child, null);
// Set the TextViews to the appropriate things
((TextView) listItem.findViewById(R.id.name)).setText(things[i].getName());
((TextView) listItem.findViewById(R.id.type)).setText(things[i].getType());
// Add the inflated view to the list
item.addView(child);
}
I have a list of articles in a listView with text on the left, and an image on the right. If the article doesn't have an image, I'd like the text to go full-width (as opposed to having a marginRight of 60dp).
My noob-java thought process is: I'm already looping through and checking if there's an image... (if there is one, I change which image shows up) within that loop, can I somehow use java to alter the XML of my view to add or remove the imageView and add or remove the margin?
The code I'm using to repeat through and alter the image:
ImageLoader imageLoader = ImageLoader.getInstance();
imageLoader.displayImage("", viewHolder.thumbView); //clears previous one
if(article.filepath != null && article.filepath.length() != 0) {
imageLoader.displayImage(
"http://img.mysite.com/processes/resize.php?image=" + article.filepath + "&size=100&quality=70",
viewHolder.thumbView
);
}
My "article_entry_list_adapter.xml":
<?xml version="1.0" encoding="utf-8"?>
<!-- Layout for individual news entries in a list -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<!-- Title of the news entry -->
<TextView
android:id="#+id/article_title"
android:layout_width="fill_parent"

<!-- Subtitle contains author and date -->

android:layout_marginRight="60dp"
android:layout_alignLeft="#id/article_title"
android:layout_below="#id/article_title"

android:layout_alignParentRight="true"
android:background="#color/super_light_gray"
android:padding="1dp"
android:scaleType="centerCrop" android:cropToPadding="true"/>
</RelativeLayout>
I would suggest changing your xml layout to something like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp" >
<!-- Title of the news entry -->
<com.sltrib.views.WebImageView
android:id="#+id/article_thumbnail"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignParentRight="true"
android:adjustViewBounds="true"
android:background="#color/super_light_gray"
android:cropToPadding="true"
android:padding="1dp"
android:scaleType="centerCrop"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginRight="5dip"
android:layout_toLeftOf="#id/article_thumbnail"
android:orientation="vertical" >
<TextView
android:id="#+id/article_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Titol"
android:textColor="#drawable/list_title_selector"
android:textSize="13sp"
android:textStyle="bold"
android:typeface="serif" />
<TextView
android:id="#+id/article_subtitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Subtitol"
android:textColor="#drawable/list_subtitle_selector"
android:textSize="11sp" />
</LinearLayout>
Then, when there is no image, just set the WebImageView visibility to GONE and the text will take the parent's width.
With your example:
viewHolder.thumbView.setVisibility(View.VISIBLE); //to show the image
viewHolder.thumbView.setVisibility(View.GONE); //to hide the image
You can either alter your viewGroup (setting visibility of your imageView to GONE and adding a margin programmatically) or choose to inflate another xml. As you want to do =)
Just while looping setVisiblity(VIEW.Gone) of article_thumbnail.
TextView textView = (TextView) findViewById(R.id.textView1);
LinearLayout.LayoutParams llp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
llp.setMargins(50, 0, 0, 0); // llp.setMargins(left, top, right, bottom);
textView.setLayoutParams(llp);
