As per the standrad recomendation we should use DialogFragment instead of common dialog for showing message on dialog window.
A fragment display dialog window on top of it's activity window.
For more information read
DialogFragment.
Here I am going to create dialog which will be the common for whole application.
import android.app.DialogFragment;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
public class MainActivity extends AppCompatActivity implements CustomDialogFragment.DialogCallBack {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.btnOnClick).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog();
}
});
}
void showDialog() {
DialogFragment newFragment = CustomDialogFragment.newInstance(
R.string.title, R.string.message);
newFragment.onAttach(this);
newFragment.show(getFragmentManager(), "dialog");
}
@Override
public void dialogPositiveCallBack() {
Log.i("FragmentAlertDialog", "Positive click!");
}
}
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:id="@+id/btnOnClick"
android:text="Click Me"
android:onClick="submit"
android:layout_height="wrap_content" />
</RelativeLayout>
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.DialogInterface;
import android.os.Bundle;
public class CustomDialogFragment extends DialogFragment {
private DialogCallBack mDialogCallBack;
public CustomDialogFragment() {
}
public static CustomDialogFragment newInstance(int title, int message) {
CustomDialogFragment frag = new CustomDialogFragment();
Bundle args = new Bundle();
args.putInt("title", title);
args.putInt("message", message);
frag.setArguments(args);
return frag;
}
public interface DialogCallBack {
void dialogPositiveCallBack();
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
mDialogCallBack = (DialogCallBack) activity;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Bundle args = getArguments();
int title = args.getInt("title", 0);
int message = args.getInt("message", 0);
return new AlertDialog.Builder(getActivity())
.setTitle(title)
.setMessage(message)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (mDialogCallBack != null) {
mDialogCallBack.dialogPositiveCallBack();
}
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.create();
}
}
In the same way you can create negative callback, interface given below.
public interface DialogCallBack {
void dialogPositiveCallBack();
void dialogNegativeCallBack();
}
please comment if anything need to support.
