The problem is in DemoPopupWindow.onCreate method:
ViewGroup root = (ViewGroup) inflater.inflate(
R.layout.popup_grid_layout, null);
for (int i = 0, icount = root.getChildCount(); i < icount; i++) {
View v = root.getChildAt(i);
if (v instanceof TableRow) {
root will be RelativeLayout defined in popup_grid_layout.xml. Later you iterate through all its children and set onclick listeners only if child view is TableRow, which is never the case. I guess what you want there is to find horizontalScrollView1 view and do the same with its children instead, something like:
View horizontalScrollView1 = findViewById(R.id.horizontalScrollView1);
for (int i = 0, icount = horizontalScrollView1.getChildCount(); i < icount; i++) {
View v = horizontalScrollView1.getChildAt(i);
if (v instanceof TableRow) {

Unable to Draw lines between two listviews or list of buttons in horizontal

Presently I am getting buttons in both columns but unable to draw lines either you can do this buttons stuff by using listview as well. can you please help me with this. Thanks in advance.

divide your cross line in two parts.
try the below code,
MainActivity.java
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerview=findViewById(R.id.recyclerview);
recyclerview.setLayoutManager(new LinearLayoutManager(this));
recyclerview.setAdapter(new SampleAdapter());
}
}
SampleAdapter.java
public class SampleAdapter extends RecyclerView.Adapter<SampleAdapter.MyViewHolder> {
ArrayList<String> list1;
ArrayList<String> list2;
public SampleAdapter() {
list1 = new ArrayList<>();
list2 = new ArrayList<>();
for (int i = 1; i <= 20; i++) {
list1.add("Left " + i);
list2.add("Right " + i);
}
}
#NonNull
#Override
public SampleAdapter.MyViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.recycle_item, viewGroup, false);
return new SampleAdapter.MyViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull SampleAdapter.MyViewHolder myViewHolder, int position) {
myViewHolder.buttonLeft.setText(list1.get(position));
myViewHolder.buttonRight.setText(list2.get(position));
//show partA image
if (position == 8) {
myViewHolder.imageview1.setVisibility(View.GONE);
myViewHolder.imageview2.setVisibility(View.VISIBLE);
}
//show partB image
if (position == 9) {
myViewHolder.imageview1.setVisibility(View.GONE);
myViewHolder.imageview3.setVisibility(View.VISIBLE);
}
}
#Override

Android radiogroup with nested linearlayouts not deselecting radiobuttons [duplicate]

This question already has answers here:
How to group RadioButton from different LinearLayouts?
(21 answers)
Closed 5 years ago.
I have a group of radiobuttons in a radiogroup that refuses to behave the way I'd like. The radiobuttons need to be two lines of two, and one line of one, with the last button having an edittext instead of a label. The layout looks correct, but the radiobuttons allow more than one to be selected and won't deselect any.
Below is my XML:
<RadioGroup
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rgDesignation">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/llVT1">
<RadioButton
android:text="#string/pressure_equipment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbPE"
android:layout_weight="1" />
<RadioButton
android:text="#string/assemblies"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbAss"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"

android:layout_height="wrap_content"
android:id="#+id/rbUnh"

<RadioButton
android:text="#string/heated"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbH"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout

Try Changing
**<View
android:id="#+id/overlay"
android:layout_width="260dp"
android:layout_height="20dp"
android:layout_below="#+id/lbl_balance" />**
to
**<View
android:id="#+id/overlay"
android:layout_width="260dp"
android:layout_height="20dp"
android:layout_alignBottom="#+id/heart_ImageView" />**
Changes made: layout alignment and the id of to whom it was aligned

You can try adding rules to the params with the addRule method
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
I'm not near my PC to test, but you may be able to set the view below lbl_balance with the addRule method
Or, try removing the layout params in the code all together. The xml inflates the view, so it is already created. All you need to do in code is set the background color. Which you can also do in the xml with
android:background="#80000000"

Android expand and contract animation on Layout

I have a normal Relative Layout with text view and progress bar.
Now, since i have a fixed width and height of the layout the text is properly placed in the center and looks good, onclick of layout we are changing the visibility of progress bar to "Visible", but since i have a fixed width the progress bar is on top of the text.
What i am trying to achieve is , onclick increase the right end width of the layout along with animation.
Here is my code :
<RelativeLayout
android:id="#+id/rellyt"
android:layout_width="150dp"
android:layout_height="35dp"
android:layout_margin="5dp"
android:background="#B7E4FF"
android:clickable="true" >
<TextView
android:id="#+id/txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:text="click on this button"
android:textColor="#000000"
android:textSize="14sp" />
<ProgressBar
android:id="#+id/prgbar"

Animation
public class ResizeWidthAnimation extends Animation
{
private int mWidth;
private int mStartWidth;
private View mView;
public ResizeWidthAnimation(View view, int width)
{
mView = view;
mWidth = width;
mStartWidth = view.getWidth();
}
#Override
protected void applyTransformation(float interpolatedTime, Transformation t)
{
int newWidth = mStartWidth + (int) ((mWidth - mStartWidth) * interpolatedTime);
mView.getLayoutParams().width = newWidth;
mView.requestLayout();
}
#Override
public void initialize(int width, int height, int parentWidth, int parentHeight)
{
super.initialize(width, height, parentWidth, parentHeight);
}
#Override
public boolean willChangeBounds()
{
return true;
}
}
Usage
if(animate)
{
ResizeWidthAnimation anim = new ResizeWidthAnimation(leftFrame, leftFragmentWidthPx);
anim.setDuration(500);
leftFrame.startAnimation(anim);
}
else
{
this.leftFragmentWidthPx = leftFragmentWidthPx;
LayoutParams lp = (LayoutParams) leftFrame.getLayoutParams();
lp.width = leftFragmentWidthPx;
leftFrame.setLayoutParams(lp);
}
