This View is supposed to make a Button for each LinearLayout inside itself, and put that LinearLayout inside a ScrollView. I think the problem is that the LinearLayouts don't exist yet, since they are created AFTER initializing this view. Therefore getChildCound() returns zero. You could work around this by hard coding the number of Buttons or getting it from a XML attribute, but you can't put the LinearLayouts in the ScrollViews, when there are no LinearLayouts. Is there a way to work around this?

for(int i = 0; i < lls.size(); i++){
if(btns[i] == null){
Log.e("error: ", "Please add more Button lables to the strings.xml file.");

The idea is that you need to put your logic into onLayout
Something like this:
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
final Context context = c;
final int count = this.getChildCount();
TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.accordion);
String[] btns = getResources().getStringArray(R.array.buttons);
ArrayList<LinearLayout> lls = new ArrayList <> (count);
for(int i = 0; i < count; i++){
View child = this.getChildAt(i);
if (child instanceof LinearLayout) {
lls.add((LinearLayout)child);
}
}
.......
See this
Make sure that you call child.layout() for each child inside this method.
You can create custom LinearLayout inside ScrollView:
<ScrollView>
<LinearLayout android:id="#+id/parent"/>
</ScrollView>
Then Create java class for your layout and inflate it.

I have tried adding the blocksDescendants code in my activity_main.xml under Listview, and Relativelayout, but that doesn't seem to fix it. I also tried setting the focusable property to false for the imageview and textview but that didn't fix it either.
I have a RecyclerView with a LinearLayout inside. The LinearLayout consists out of 9 buttons. Before some changes I could click the buttons and it didn't crashed. But after I added this code below it gives the error and does not show where it comes from:
java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams
cannot be cast to android.support.v7.widget.RecyclerView$LayoutParams
The imports in Adapter:
import android.content.Context;
import android.graphics.Color;
import android.support.v7.widget.RecyclerView;
import android.widget.LinearLayout.LayoutParams;
import android.util.TypedValue;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;
Added this in the onClickListener:
tempTag = (int) v.getTag();
mAdapter.grayButton(tempTag / 9, tempTag % 9);
zahl1 = Integer.parseInt(mAdapter.getText(tempTag).toString());
Added this method in the RecyclerView.Adapter:
public void grayButton(int row, int element){
recycleViewDatas.get(row).setGray(element);
notifyItemChanged(row);
}
Added this code in the onBindViewHolder:
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
viewHolder.ll.setLayoutParams(lp);
lp.height = viewHolder.ll.getLayoutParams().height - (int) (viewHolder.buttons.get(j).getLayoutParams().height - recycleViewDatas.get(i).getSize()) + 30;
viewHolder.ll.setLayoutParams(lp);
if(recycleViewDatas.get(i).getGray() == j)
viewHolder.buttons.get(j).setTextColor(Color.GRAY);
else if(recycleViewDatas.get(i).getGray() == -1)
viewHolder.buttons.get(j).setTextColor(Color.BLACK);
This is my ViewHolder:
public static class ViewHolder extends RecyclerView.ViewHolder {
LinearLayout ll;
private ArrayList<Button> buttons = new ArrayList<>();
public ViewHolder(View v, Context context) {
super(v);
ll = (LinearLayout) v.findViewById(R.id.llRecycleView);
for (int i = 0; i < ll.getChildCount(); i++) {
buttons.add((Button) ll.getChildAt(i));
}
}
}
The layout file of the recycleviewdata:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="9"

android:id="#+id/llRecycleView">

android:textColor="#android:color/black"
android:background="#android:color/transparent"
android:textSize="23sp"
android:clickable="false"
android:layout_gravity="center"
android:gravity="center" />
...more buttons
The layout of the MainActivity:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout

<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"/></LinearLayout>
I do not understand why the error comes after the update. And the app only crashes on my M9. On the HTC One V it does not crash and all works as expected.
You know the problem? Do you need any more code?
Your problem is in onBindViewHolder:
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
LayoutParams is implemented for (almost) all the layouts.
When you set LayoutParams on a view, you need to set it with a type of the view's parents. So if you have a LinearLayout and you are trying to add a Button, you need to set LinearLayout.LayoutParams on the Button. The problem in this case is that you don't know the parent type. And by that I mean it can different on different Android versions.
The safe bet is to use the LayoutParams from a common class (ViewGroup?) since you only set width and height.
i had same problem, you can use this
ViewGroup.LayoutParams layoutParams =v.itemView.getLayoutParams();
layoutParams.width= ViewGroup.LayoutParams.MATCH_PARENT;
layoutParams.height= 200;
v.itemView.setLayoutParams(layoutParams);
if you need the kotlin version :
with(view.layoutParams){
width = ViewGroup.LayoutParams.WRAP_CONTENT
height = ViewGroup.LayoutParams.MATCH_PARENT
}
I have a ViewPager that I want to take the full-screen, but it only takes part of it. How can I make it take the full-screen? Here's my code, notice that it is filled with many calls to make the layout take the full-screen, to no avail.

}
And this is how it looks (the image is 1080*1920):
Edit: I basically want to do a mini tutorial. One page with images, one page with a movie. What do you think is the best way?
Try this:
int deviceWidthInPixels = getResources().getDisplayMetrics().widthPixels;
int deviceHeightInPixels = getResources().getDisplayMetrics().heightPixels;
imageView.getLayoutParams().width = deviceWidthInPixels;
imageView.getLayoutParams().height = deviceHeightInPixels;
Also, use this for ViewPager:
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
And this for ImageView
<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/image_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY" />
Try 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" >
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_margin="5dp"
/>
</LinearLayout>
our code
android:layout_width="fill_parent"
android:layout_height="fill_parent"
Change it to
android:layout_width="match_parent"
android:layout_height="match_parent"
Or you can try this adding to your ViewPager
android:layout_height="0dp"
android:layout_weight="1"
Let me know if further issue exists
-Now i saw your lines
LayoutParams lp = new LayoutParams(width, height);
Change it to Below code:-
Layoutparams lp = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
I feel so stupid... Notice that in my onCreate I have getWindow().setLayout(Main.screenWidth, Main.screenHeight) Annoyingly I made Main.screenHeight) to be 75 % :( Removing it fixed my problem.

TableRow.LayoutParams rowParams = new TableRow.LayoutParams();
rowParams.width = LayoutParams.WRAP_CONTENT;
rowParams.height = LayoutParams.WRAP_CONTENT;
mCircles = new View[ROWS][COLS];
TableRow row;
for (int i = 0; i < ROWS; i++) {
row = new TableRow(this);
row.setLayoutParams(rowParams);
for (int j = 0; j < COLS; j++) {
mCircles[i][j] = new View(this);
mCircles[i][j].setBackgroundResource(R.drawable.small_circle);
row.addView(mCircles[i][j]);

Your help appreciated...
I think it is the "View" that is giving you a problem. Try replacing it with an ImageView (try it) and I think it will work. If you really want View (not sure why) then set the min height and min width to something like 10dp.
It happened to me once that empty View with wrap content spans the whole page. It is pushing the rest of your rows out of the screen
I am setting a listView dynamically. I will have two things shown on each line that I will be receiving from parse.com. I want the first thing to be left aligned and blue, with the second thing right aligned and red. I will have two arrays, firstArray, and secondArray. I found lots of ways to do this, but none dynamically. How should I go about doing this, or I can do it in xml?
Updated
This is my xml after that tutorial posted by #t0s

public class DataItem {
private String name;
private String record;
public DataItem(){
}
public DataItem(String n, String r ){
this.name = n;
this.record = r;
}
public String getname() {
return name;
}
public void setname(String name) {
this.name = name;
}
public String getrecord() {
return record;
}
public void setrecord(String record) {
this.record = record;
}
}
CustomAdapter :
package org.example.chad;
import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
public class CustomAdapter extends ArrayAdapter<DataItem> {
private ArrayList<DataItem> objects;
public CustomAdapter(Context context, int textViewResourceId, ArrayList<DataItem> objects) {
super(context, textViewResourceId, objects);
this.objects = objects;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.row, null);
}
DataItem i = objects.get(position);
if (i != null) {
TextView nameView = (TextView) v.findViewById(R.id.name);
TextView recordView = (TextView) v.findViewById(R.id.record);
if (nameView != null){
nameView.setText(i.getname());
}
if (recordView != null){
recordView.setText(i.getrecord());
}
}
return v;
}
}
and row.xml :
<?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="match_parent"
android:orientation="horizontal" >
<TextView
android:id="#+id/name"
android:layout_width="100sp"
android:layout_height="20sp"
android:textSize="16sp"
android:layout_gravity="left|center_vertical"
android:layout_marginLeft="10sp"/>
<TextView
android:id="#+id/record"
android:layout_width="100sp"
android:layout_height="wrap_content"
android:layout_marginLeft="10sp"
android:layout_gravity="right"
android:textSize="16sp" />
</LinearLayout>
In a couple of hours I will add some comments.
The result is here
If im not mistaken you have to extend BaseAdapter class so you have a custom Adapter for your ListView, it is not possible to add two array items to a ListView without creating a custom adapter.
here is a tutorial.
is not as hard as it looks like. Hope it helps.
