I have a ListView displaying some text on my android activity. The problem I am facing is that some text is bigger than the other so the ListView rows don't have the same size.
I would like to have all the rows the size of the biggest. That way all the text will be display and they will all have the same size.
Here is my xml :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<CheckBox
android:id="#+id/favorite_checkbox"
android:layout_width="0dp"
android:layout_height="fill_parent"
style="?android:attr/starStyle"
android:layout_weight="1"
/>
<TextView
android:id="#+id/IdText"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="2"
/>
<TextView
android:id="#+id/StationNameText"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="2"
/>
</LinearLayout>
</LinearLayout>
Thanks for your time.
You can get the height of the 'tallest' view programmatically - How to get an Android widget's size after layout is calculated?, and then set that height to your other layouts.
I would do something like this:
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int width = displaymetrics.widthPixels;
int HeightOfTallestView = //method you choose from link above
IdText.setLayoutParams(new LinearLayout.LayoutParams(width, HeightOfTallestView ));
Please let me know if this works for you.

How to fill a ConstraintLayout with two radioButtons inside of a RadioGroup? I can't find a way to do it. I post here two images, one is how I want to make it look, and the other is how it looks right now with my code.
This is how it looks right now
This is how I want
<androidx.constraintlayout.widget.ConstraintLayout

android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"

android:button="#color/transparent"
android:elevation="4dp"
android:padding="16dp"
android:text="Contrarreembolso"
android:textAlignment="center" />
</RadioGroup>
</androidx.constraintlayout.widget.ConstraintLayout>
The best thing that I could do after reading some answers on StackOverflow and trying many things is to get to this point:
I have taken this layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<RadioGroup
android:layout_width="0dp"
android:layout_height="0dp"
android:orientation="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<RadioButton
android:id="#+id/radioButton"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_gravity="center"
android:background="#193312"
android:elevation="4dp"
android:text="Paypal"
android:textAlignment="center" />
<RadioButton
android:id="#+id/radioButton2"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#122B33"
android:elevation="4dp"
android:gravity="center"
android:text="Contrarreembolso"
android:textAlignment="center" />
</RadioGroup>
</androidx.constraintlayout.widget.ConstraintLayout>
And used this code to get the height of the screen and put half of it on my views, inside your activity:
#Override
protected void onStart() {
super.onStart();
//Get the height is the screen
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int height = size.y;
DisplayMetrics displayMetrics = new DisplayMetrics();
RadioButton radioButton1 = findViewById(R.id.radioButton);
RadioButton radioButton2 = findViewById(R.id.radioButton2);
//Give view half of the screen height
ViewGroup.LayoutParams params = radioButton1.getLayoutParams();
params.height = (height)/2;
ViewGroup.LayoutParams params2 = radioButton2.getLayoutParams();
params2.height = (height)/2;
}
Notice that this layout is not perfect looking, your radio buttons do spread across your device in height but they are not equal, the one thing left to do if you want your button to be equal in height is to calculate the action bar height and take it into account.
I build a custom dialog to pop up an image with close button like this:
As you can see the dialog is not fitting the dialog layout and there's this white borer on the top and on the right, so how can i get rid the white border thing and make my custom dialog fit?
<?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:layout_gravity="center_vertical"
android:gravity="center"
android:orientation="vertical" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" >
<LinearLayout
android:id="#+id/linearMain"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:layout_marginTop="10dp"
android:gravity="center"
android:orientation="vertical"
android:paddingBottom="-50dp" >
<ImageView
android:id="#+id/imgMain"
android:layout_width="300dp"
android:layout_height="350dp"
android:gravity="center"
android:background="#drawable/eairh_dialog"
/>
<!---add your views here-->
</LinearLayout>
<ImageView
android:id="#+id/imgClose"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top|right"
android:clickable="true"
android:src="#drawable/close_button" />
</FrameLayout>
</LinearLayout>
getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
Use Above Code in your Dialog class to make Dialog TransParent
Remove margin Top and right on LinearLayout:
android:layout_marginRight="5dp"
android:layout_marginTop="10dp"
To make the Dialog bigger, you can set those parameters to MATCH_PARENT.
int screenWidth = 0, screenHeight = 0 ;
Display display = thid.getWindowManager().getDefaultDisplay();
screenWidth = display.getWidth();
screenHeight = display.getHeight();
Dialog dialog = new Dialog(getActivity(), android.R.style.Theme_DeviceDefault);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.cart_empty);
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(dialog.getWindow().getAttributes());
lp.width = screenWidth;
lp.height = screenHeight;
dialog.getWindow().setAttributes(lp);
dialog.show();
I've been trying to figure out how to place a container that fills the entire screen vertically inside a ScrollView that has content below.
Something like this:
[ BOX THAT FILLS ENTIRE SCREEN ]
[ Some other stuff / requires scroll to view ]
This is the content I would like below the box:
http://myupload.dk/handleupload/ce34836ostt
I've tried everything - it seems like i can't position stuff absolute to the container that fills the entire screen. I can make a box that fills the entire screen, but everything i adds below it squeezes the box together.
It works when I add a size to the box, like this:
<com.github.ksoichiro.android.observablescrollview.ObservableScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|top"
android:minWidth="25px"
android:minHeight="0px"
android:paddingTop="0dp"
android:fillViewport="true"
android:id="#+id/scroll">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- THIS BOX I WOULD LIKE TO FIT THE ENTIRE SCREEN -->
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="100dp"
android:id="#+id/cardsPager" />
<!-- THIS CONTENT SHOULD BE BELOW THE BOX ABOVE -->
<fragment android:name="bonnier.hvadsynes.fragments.DetailsFragment"
android:id="#+id/details_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</com.github.ksoichiro.android.observablescrollview.ObservableScrollView>
Really appreciate your help!

My idea is to set the height of the screen-filling-box programmatically.
When and Where: depends on what you use e.g.in onResume there surely are better places but for now it works.
How: add an OnGlobalLayoutListener to your viewtreeobserver and then copy your scrollviews height to 'the box'.
<!--Whatever the whole things height should be, e.g. match_parent or 100dp or or or-->
<ScrollView
android:background="#0f0"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/scrollview">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- THIS BOX I WOULD LIKE TO FIT THE ENTIRE SCREEN -->
<!-- Any height works as we overwrite it anyway-->
<View
android:id="#+id/makebig"
android:background="#f00"
android:layout_width="match_parent"
android:layout_height="300dp" />
<!-- THIS CONTENT SHOULD BE BELOW THE BOX ABOVE -->
<View
android:background="#0ff"
android:id="#+id/details_fragment"
android:layout_width="match_parent"
android:layout_height="100dp"/>
</LinearLayout>
</ScrollView>
In your Activity or wherever: e.g. in onResume()
final View makebig = findViewById(R.id.makebig);
final View scrollview = findViewById(R.id.scrollview);
final ViewTreeObserver viewTreeObserver = scrollview.getViewTreeObserver();
viewTreeObserver.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
//only do this all once
scrollview.getViewTreeObserver().removeOnGlobalLayoutListener(this);
makebig.getLayoutParams().height = scrollview.getHeight();
}
});
You can do it this way:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/layout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#A5CB3A"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/layout2"
android:layout_width="match_parent"
android:layout_height="200dp"
android:orientation="vertical" >
<!-- here goes your textview -->
</LinearLayout>
</LinearLayout>
And in the onCreate method of the Activity
Point size = new Point();
getWindowManager().getDefaultDisplay().getSize(size);
int screenHeight = size.y;
LinearLayout layout = (LinearLayout)findViewById(R.id.layout1);
ViewGroup.LayoutParams params = layout.getLayoutParams();
params.height = screenHeight; //here you can substract the height of the top bar, if your app has one
layout.setLayoutParams(params);
You are just setting the height of the screen to the inner layout.
I would like to make an activity with this structure:
The idea is to put some text in the top, a banner allways in the top, the button OVER the banner and my canvas in the center of the view, using all the possible space.
I'm subclassing View to draw my canvas and overloading the onMeasure() method:
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// Calculate the size of the board
this.squareSize = MeasureSpec.getSize(widthMeasureSpec) / BOARD_NUM_ROWS;
this.leftMargin = (MeasureSpec.getSize(widthMeasureSpec) - squareSize*BOARD_NUM_COLUMNS) / 2;
this.topMargin = this.leftMargin;
// Set the size of the board to full width and aspect ratio height
int desiredWidth = MeasureSpec.getSize(widthMeasureSpec);
int desiredHeight = this.topMargin + (BOARD_NUM_ROWS * this.squareSize) + this.topMargin;
this.setMeasuredDimension(desiredWidth, desiredHeight);
}
And this is my XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".DrawLevelActivity"
android:background="#color/activity_background">
<TextView
android:id="#+id/instructionsText"
android:gravity="center"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<com.mycanvas.BoardCanvas
android:id="#+id/boardCanvas"
android:gravity="center"
android:layout_below="#+id/instructionsText"
android:layout_centerVertical="true"
android:padding="0dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/solveButton"
android:gravity="center"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:paddingLeft="30dp"
android:paddingRight="30dp"
android:layout_below="#+id/boardCanvas"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<com.google.ads.AdView
xmlns:googleads="http://schemas.android.com/apk/lib/com.google.ads"
android:id="#+id/adView"
android:gravity="center"
android:paddingTop="0dp"
android:paddingBottom="0dp"
android:paddingLeft="0dp"
android:paddingRight="0dp"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
googleads:adSize="BANNER"
googleads:adUnitId="#string/admob_id" />
</RelativeLayout>
Unfortunately the button appear under the banner and I think that the reason is that the canvas is very large.
The set value in onMeasure() is always smaller than MeasureSpec.getSize(heightMeasureSpec)
The key here is to use a LinearLayout setting a layout_weight value just for your canvas. This way, the top and above views will wrap their content, and the canvas will fill the free space. The layout xml would look like this.-
<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="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="50dp"
android:gravity="center_vertical|center_horizontal"
android:background="#990099"
android:text="Some text here" />
<RelativeLayout
android:id="#+id/canvas"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#999900"
android:layout_weight="1">
<!-- The canvas -->
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button" />
<RelativeLayout
android:id="#+id/banner"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#009999">
<!-- The banner -->
</RelativeLayout>
</LinearLayout>
Notice I set some hardcoded heights and colors so that you can easily see the results. This layout will render a view like this.-
Right now I have this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical"
android:weightSum="5">
<TextView
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<VideoView
android:id="#+id/video"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="4"/></LinearLayout>
It actually works the problem is the video. It doesn't take full width of the LinearLayout. I have tried with:
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int width = displaymetrics.widthPixels;
video.setLayoutParams(new LinearLayout.LayoutParams(width,LayoutParams.MATCH_PARENT,4f));
But didn't work.
I want to have something like this:
****text****
------------
************
***video****
************
Thanks
