Ich habe versucht, mit AlertDialog anstelle von PopupWindow. Es funktioniert gut auf meiner Seite, versuchen Sie es, wenn es das ist, wonach Sie suchen.

import android.content.DialogInterface; 
import android.os.Bundle; 
import android.support.design.widget.FloatingActionButton; 
import android.support.v7.app.AlertDialog; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.Toolbar; 
import android.view.View; 
import android.widget.LinearLayout; 
import android.widget.NumberPicker; 

public class MainActivity extends AppCompatActivity { 
    final String month[] = {"jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec"}; 
    final String sub[] ={"Airlaw","criminal","Income tax","Direct tax","Customs", "Defence & Security Forces" , "Disinvestment" , "Education" , "Election" , 
      "Electricity & Energy" , "Environment, Wildlife & Animal", "Exchange Control & FDI " , "Excise"}; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     final ImageButton button = (ImageButton) findViewById(R.id.imageButton);    
     button.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       openDialog(); 
      } 
     }); 
    } 

    /** 
    * This will construct An {@link AlertDialog} with some custom views. 
    */ 
    private void openDialog() { 
     //Inflating a LinearLayout dynamically to add TextInputLayout 
     //This will be added in AlertDialog 
     final LinearLayout linearLayout = (LinearLayout) getLayoutInflater().inflate(R.layout.view_number_dialog, null); 
     NumberPicker numberpicker = (NumberPicker) linearLayout.findViewById(R.id.numberPicker1); 
     NumberPicker numberPicker1 = (NumberPicker) linearLayout.findViewById(R.id.numberPicker2); 
     NumberPicker numberPicker2 = (NumberPicker) linearLayout.findViewById(R.id.numberPicker3); 

     numberpicker.setMinValue(1950); 
     numberpicker.setMaxValue(2018); 
     numberpicker.setValue(2017); 
     numberPicker1.setMinValue(0); 
     numberPicker1.setMaxValue(month.length - 1); 
     numberPicker1.setDisplayedValues(month); 
     numberPicker1.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS); 
     numberPicker2.setMinValue(0); 
     numberPicker2.setMaxValue(sub.length - 1); 
     numberPicker2.setDisplayedValues(sub); 
     numberPicker2.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS); 
     //Finally building an AlertDialog 
     final AlertDialog builder = new AlertDialog.Builder(this) 
       .setPositiveButton("Submit", null) 
       .setNegativeButton("Cancel", null) 
       .setView(linearLayout) 
       .setCancelable(false) 
       .create(); 
     builder.show(); 
     //Setting up OnClickListener on positive button of AlertDialog 
     builder.getButton(DialogInterface.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       // Code on submit 
      } 
     }); 
    } 
} 

view_number_dialog.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="260dp" 
    android:orientation="horizontal" 
    android:padding="14dp"> 

    <NumberPicker 
     android:id="@+id/numberPicker1" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" /> 

    <NumberPicker 
     android:id="@+id/numberPicker2" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_marginLeft="14dp" 
     android:layout_marginRight="14dp" 
     android:layout_weight="1" /> 

    <NumberPicker 
     android:id="@+id/numberPicker3" 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" /> 
</LinearLayout> 

Es wird ausgegeben, wie folgend ...
