View is not added when using addView()

I am making a window to open an empty dialog and write comments.
The dialog initially has an empty item where i can write one comment.
Comments can be up to one line.
Pressing the Enter key dynamically creates an item that allows you to write the next comment.
I was wondering whether to use RecyclerView or addView() for this function.
Since this dialog was also opened from the recycler view item of the parent, it would be complicated when using RecyclerView again, so I used addView().
I don't know if this is the right choice.
This is because data management seems to be difficult because the created comment must be saved in the parent's recycler view item.
Anyway, using addView() does not add the view.
There is no such thing as an error, but it cannot be added.
What is the cause?

your problem is that you added a horizontal LinearLayout and after you added an EditText with android: layout_width = "match_parent" that's why your Comment is added on your container view but is not visible because of the EditText.
if I understood correctly you must change
android: orientation = "horizontal" by android: orientation = "vertical" in your fragment_writing_comment_dialog
so that the commentary will be displayed above the EditText
And also you need to change the orientation on your Container LinearLayout

popup window button not working

I am developing app having a popup window showing successfully but button inside is not working. When the button is click the event is not listening. The code is shown below.
private void showPopup() {
//LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View customView = inflater.inflate(R.layout.popup_layout,null);
mPopupWindow = new PopupWindow(
customView,
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT
);
Button btn_popup_submit = (Button)customView.findViewById(R.id.btn_popup_submit);
Button btn_popup_cancel = (Button)customView.findViewById(R.id.btn_popup_cancel);
btn_popup_submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "aaa", Toast.LENGTH_SHORT).show();
Log.d("LOG","aaaa");
}
});
btn_popup_cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "bbbb", Toast.LENGTH_SHORT).show();
Log.d("LOG","bbbb");
}
});
if(Build.VERSION.SDK_INT>=21){
mPopupWindow.setElevation(5.0f);//5.0f
}
mPopupWindow.showAtLocation(mRelativeLayout, Gravity.CENTER,0,0);
mPopupWindow.setFocusable(true);
mPopupWindow.setBackgroundDrawable(new ColorDrawable(ContextCompat.getColor(mContext, android.R.color.transparent)));

The button names are btn_popup_submit and btn_popup_cancel.
I tried different methods but the problem. I don't know where is the problem facing. Please help me thanks.

Replace this line of code.Allow popWindow Touch.
mPopupWindow.setTouchable(false);
to
mPopupWindow.setTouchable(true);

using scrollview to show button behind edittext keyboard

I have a layout in which I have an image,textview, editbox and a button so whenever the keyboard opens I wanted my screen to scroll down to the button so that the user can always type and press submit button. I did do this by using scrollview but than I removed the scroll view did some changes and now when I again use a scrollview it does not work.
here is the code please check.

and in my main activity I am using the scrollto method to go to my image button.
public class MainActivity extends AppCompatActivity {
ImageButton submit;
EditText feedBack;
static public String saveFeedBack="";
ScrollView view;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
submit = (ImageButton) findViewById(R.id.submit);
feedBack = (EditText) findViewById(R.id.feedback);
view = (ScrollView) findViewById(R.id.scroll);
view.scrollTo(submit.getScrollX(),submit.getScrollY());
}
public void onSubmit(View view){
saveFeedBack = feedBack.getText().toString();
if(saveFeedBack.length() >=4) {
Intent intent = new Intent(this, Main3Activity.class);
startActivity(intent);
}
else{
Toast.makeText(getApplicationContext(),"Enter valid Feedback please.",Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onRestart() {
super.onRestart();
feedBack.setText("");
feedBack.setHint("Enter Feedback");
}
}
but when I run my application the scrollview scrolls to my edit text but not my button. I have tried adjustResize,adjustPan and all those things but none of them worked.

ok after much of research I have solved your problem. Actually the thing is when you use scroll to any position inside onCreate it doesn't work because a small delay is required to inflate the view.
So use the below code inside your onCreate:
view.postDelayed(new Runnable() {
#Override
public void run() {
view.fullScroll(ScrollView.FOCUS_DOWN);
}
},200);
Hope it Helps!!!

Dynamic View not being created in proper place. Overlapping previous view. Android

I am new to Android so I've been trying to tweak around for the past couple days but am stuck at this part. For my app, I'm trying to input a Button "Add More" which inflates a view to help incorporate user input but I'm running into issues. I looked around and I used his source code to help with my issue but I am running into the problem that my inflated xml layout is overlapping my previous set-up layout.
This is the layout that I have setup for my new_class_container file

This is how the layout for the code above looks like and I want to be able to press the "Add More" Button and it inflates to "create a new row", per say, of the TextViews of Assignment Type and Grade Weight and EditTexts of the respective TextViews. But when I run the app and press add more, the new set of TextView + EditText pop up right on top of what I have rather than underneath. The following is my other xml file new_class
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/register_assign_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="#string/write_assignment_type"
android:textAppearance="?android:attr/textAppearanceMedium"/>
<TextView
android:id="#+id/register_weight_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="#string/write_assign_percent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_marginLeft="30dp"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:id="#+id/register_assign_edit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:hint="#string/example_assign"
android:singleLine="true">
</EditText>
<EditText
android:id="#+id/register_weight_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="#string/example_weight"
android:layout_marginLeft="30dp"
android:gravity="center_horizontal"
android:inputType="number"
android:singleLine="true">
</EditText>
</LinearLayout>
</LinearLayout>
And this is the Java Code that I have
public class NewClass extends Activity{
private RelativeLayout mContainerView;
private Button mAddButton;
private View mExclusiveEmptyView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_class_container);
mContainerView = (RelativeLayout) findViewById(R.id.parentView);
mAddButton = (Button) findViewById(R.id.btnAddNewItem);
}
protected void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
//TODO: Handle Screen Rotation
}
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// TODO: Handle screen rotation:
// restore the saved items and inflate each one with inflateEditRow;
}
// onClick handler for the "Add new" button;
public void onAddNewClicked(View v) {
// Inflate a new row and hide the button self.
inflateEditRow(null);
v.setVisibility(View.GONE);
}
// onClick handler for the "X" button of each row
public void onDeleteClicked(View v) {
// remove the row by calling the getParent on button
mContainerView.removeView((View) v.getParent());
}
private void inflateEditRow(String name) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View rowView = inflater.inflate(R.layout.new_class, null);
//final ImageButton deleteButton = (ImageButton) rowView
// .findViewById(R.id.buttonDelete);
final EditText editText = (EditText) rowView
.findViewById(R.id.register_assign_edit);
if (name != null && !name.isEmpty()) {
editText.setText(name);
} else {
mExclusiveEmptyView = rowView;
//deleteButton.setVisibility(View.INVISIBLE);
}
// A TextWatcher to control the visibility of the "Add new" button and
// handle the exclusive empty view.
editText.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
if (s.toString().isEmpty()) {
mAddButton.setVisibility(View.GONE);
//deleteButton.setVisibility(View.INVISIBLE);
if (mExclusiveEmptyView != null
&& mExclusiveEmptyView != rowView) {
mContainerView.removeView(mExclusiveEmptyView);
}
mExclusiveEmptyView = rowView;
} else {
if (mExclusiveEmptyView == rowView) {
mExclusiveEmptyView = null;
}
mAddButton.setVisibility(View.VISIBLE);
// deleteButton.setVisibility(View.VISIBLE);
}
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
});
// Inflate at the end of all rows but before the "Add new" button
mContainerView.addView(rowView, mContainerView.getChildCount() - 1);
}
}
What can I do to prevent it from overlapping and showing up underneath? And how will I be able to move the button each time it's 'updated'? Because if I move the button to the new_class xml file then it won't show up originally for me to add more views.
I tried implementing the following code and what it did was enabled me to properly get a dynamic view added the first time but each time after it was overlapping the added view.
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
p.addRule(RelativeLayout.BELOW, R.id.register_assign_edit);
rowView.setLayoutParams(p);

This will work with having two layout files: main_layout and layout_to_include.

To use these layouts in your code:
....
setContentView(R.layout.main_layout);
....
llAddingContainer = (LinearLayout) findViewById(R.id.llAddingContainer);
// Clicking on this button will add another view from 'layout_to_include' to the ScrollView
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
View view = getLayoutInflater().inflate(R.layout.layout_to_include, null);
// Find the elements in this view and set them up
EditText et1 = (EditText) view.findViewById(R.id.editText1)
....
....
....
// Add the view to the LinearLayout inside ScrollView
llAddingContainer.addView(view);
});

I'm not sure, but you can try follow code to move any view. I recommend to use RelativeLayout like your main layout.
RelativeLayout.LayoutParams bParams1 = new RelativeLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
bParams1.leftMargin = (int) leftMrgn;
bParams1.topMargin = (int) topMgrn;
bParams1.height = (int) bHeight;
bParams1.width = (int) bWidth;
anyView.setLayoutParams(bParams1);

RelativeLayouts act like a FrameLayout if you don't give them any LayoutParams (constraints like below, above, center, etc.).
You can either construct the appropriate RelativeLayout.LayoutParams, or better yet, create an empty vertical LinearLayout in your first layout that will contain the rows. Then, just add the rows to the LinearLayout instead of the RelativeLayout.
