I have a custom dialog in which I include another layout. In this layout there are 3 buttons and a TextView none of these is null. If I click the buttons they work correctly. But the TextView doesn't show any text. The text should appears when I click another button. That's how it should works
Custom dialog layout:
<LinearLayout
............
.....
<androidx.cardview.widget.CardView
android:id="@+id/result_card"
android:layout_width="match_parent"
android:layout_height="wrap_content"
card_view:cardElevation="2dp"
card_view:cardMaxElevation="2dp"
android:layout_marginStart="16dp"
android:layout_marginEnd="16dp"
android:layout_marginBottom="8dp"
android:visibility="gone"
app:cardCornerRadius="8dp">
<include android:id="@+id/result_layout" layout="@layout/result_block" />
</androidx.cardview.widget.CardView>
....
....
</LinearLayout>
The result_block 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:padding="16dp"
android:background="@color/colorPrimary"
android:orientation="vertical">
<TextView
android:id="@+id/result_txt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="17dp"
android:text=""
android:textColor="@color/colorWhite"
android:fontFamily="sans-serif-medium"
android:padding="8dp"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="end"
android:orientation="horizontal">
<ImageButton
android:id="@+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_copy_24px_outlined"
android:layout_marginEnd="16dp"
android:tint="@color/colorWhite"
android:background="?attr/selectableItemBackgroundBorderless"
/>
<ImageButton
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="16dp"
android:tint="@color/colorWhite"
android:src="@drawable/ic_share_24px_outlined"
android:background="?attr/selectableItemBackgroundBorderless"
/>
<ImageButton
android:id="@+id/btn3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:tint="@color/colorWhite"
android:src="@drawable/ic_volume_up_24px_outlined"
android:background="?attr/selectableItemBackgroundBorderless"
/>
</LinearLayout>
</LinearLayout>
And now the dialog
private void showDiag() {
final View dialogView = View.inflate(getActivity(), R.layout.custom_dialog_layout,null);
final View resultLayout = View.inflate(getActivity(), R.layout.result_block,null);
final Dialog dialog = new Dialog(getActivity(), R.style.MyAlertDialogStyle);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(dialogView);
final TextView resultTxt = resultLayout.findViewById(R.id.result_txt);
final ImageButton btn1 = resultLayout.findViewById(R.id.btn1);
final CardView resultCardView = dialog.findViewById(R.id.result_card_view);
final TextInputEditText editText = dialog.findViewById(R.id.text_edit);
final ImageButton clearText = dialog.findViewById(R.id.clear_text);
MaterialButton resultConfirm = dialog.findViewById(R.id.result_confirm);
ImageButton btn2 = dialogView.findViewById(R.id.copy_btn);
ImageButton btn3 = dialogView.findViewById(R.id.share_btn);
resultConfirm.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(!editText.getText().toString().equals("")) {
String theWord = editText.getText().toString();
String result = Utils.getSecondWord(theWord);
// result it shows me the correct string with no errors or something else
resultTxt.setText(result); // doesn't work. Not set the text
insertWord(theWord, result);
resultCardView.setVisibility(View.VISIBLE);
resultCardView.setVisibility(View.VISIBLE);
} else {
Toast.makeText(getActivity(), "Error", Toast.LENGTH_SHORT).show();
}
}
});
bt1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(TAG, "result: " + resultTxt.getText().toString());
}
});
// Share btn
bt2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(TAG, "result: " + resultTxt.getText().toString());
}
});
btn3.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i(TAG, "result: " + resultTxt.getText().toString());
}
});
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
@Override
public void onShow(DialogInterface dialogInterface) {
Utils.revealShow(dialogView, true, null, resultConfirm);
}
});
dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
@Override
public boolean onKey(DialogInterface dialogInterface, int i, KeyEvent keyEvent) {
if (i == KeyEvent.KEYCODE_BACK){
Utils.revealShow(dialogView, false, dialog, resultConfirm);
return true;
}
return false;
}
});
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.show();
}
Everything inside the dialog works correctly but the TextView not. Even if I try to write something else like resultTxt.setText("Hello there"); the text not appears. Any suggestions?
