Wie man Text in NumberPicker klickbar macht

Question

Ich würde gerne wissen, ob es möglich ist, den Text innerhalb des NumberPickers klickbar zu machen und sich gleich zu verhalten, wenn ich auf den weißen Bereich oder den Textbereich klicke. Der Grund, warum ich so etwas versuche, ist, dass es sehr schwierig wird, diesen Bereich auszuwählen, wenn ich eine lange Saite in der Bar habe. Ich habe meinen Code bisher angehängt.

MainActivity.java

package com.yardimobileinterns.numberpicker; 

import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 
import android.view.View; 
import android.widget.EditText; 

public class MainActivity extends AppCompatActivity { 

    private EditText editText; 
    private String[] values = {"University1", "University2", "University3"}; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     editText = (EditText) findViewById(R.id.editText); 

     editText.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       editText.setMovementMethod(null); 
       editText.setSelection(editText.getText().length()); 

       showDialog(editText, values); 
      } 
     }); 

    } 

    public void showDialog(EditText editText, String[] values) { 
     EditTextDialogFragment editTextDialogFragment = EditTextDialogFragment.getNewInstance(editText,values); 
     editTextDialogFragment.show(getFragmentManager(), "dialog"); 
    } 

} 

EditTextDialogFragment.java

package com.yardimobileinterns.numberpicker; 

import android.app.DialogFragment; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.EditText; 
import android.widget.NumberPicker; 


public class EditTextDialogFragment extends DialogFragment { 

    public static final String EDIT_TEXT = "EDIT_TEXT"; 
    public static final String VALUES = "VALUES"; 


    private String[] mValues; 
    private NumberPicker numberPicker; 
    private EditText mEditText; 
    private String selectedValue; 


    public EditTextDialogFragment() { 

    } 

    public static EditTextDialogFragment getNewInstance(EditText editText, String[] values) { 
     EditTextDialogFragment editTextDialogFragment = new EditTextDialogFragment(); 

     Bundle bundle = new Bundle(); 

     bundle.putStringArray(VALUES, values); 
     editTextDialogFragment.setEditText(editText); 
     editTextDialogFragment.setArguments(bundle); 

     return editTextDialogFragment; 
    } 

    public void setEditText(EditText editText) { 
     mEditText = editText; 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setRetainInstance(true); 

     mValues = getArguments().getStringArray(VALUES); 
    } 

    @Override 
    public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle savedInstanceState) { 

     View view = layoutInflater.inflate(R.layout.university_picker, viewGroup, false); 

     getDialog().getWindow().setGravity(Gravity.FILL_HORIZONTAL | Gravity.BOTTOM); 

     numberPicker = (NumberPicker) view.findViewById(R.id.numberPicker); 

     numberPicker.setMinValue(0); 

     selectedValue = (mValues.length == 0) ? "" : mValues[0]; 

     numberPicker.setMaxValue(mValues.length - 1); 

     numberPicker.setDisplayedValues(mValues); 

     numberPicker.setWrapSelectorWheel(false); 

     numberPicker.setClickable(true); 

     numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() { 
      @Override 
      public void onValueChange(NumberPicker picker, int oldVal, int newVal) { 
       selectedValue = mValues[newVal]; 
      } 
     }); 

     numberPicker.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       getDialog().dismiss(); 
       mEditText.setText(selectedValue); 
      } 
     }); 


     return view; 
    } 

} 

university_picker.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.yardimobileinterns.numberpicker.MainActivity" 
    android:background="#ffffff"> 

    <NumberPicker 
     android:id="@+id/numberPicker" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:descendantFocusability="blocksDescendants" 
     > 

    </NumberPicker> 

</RelativeLayout> 

Hier ist, wie es aussieht: Dank!

Die eigentliche Lösung, die ich gefunden habe, war onClick mit onTouch zu emulieren, um den Text klicken zu können. Es funktioniert jetzt gut.

package com.yardimobileinterns.numberpicker; 

import android.app.DialogFragment; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.LayoutInflater; 
import android.view.MotionEvent; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.EditText; 
import android.widget.NumberPicker; 


public class EditTextDialogFragment extends DialogFragment { 

    public static final String EDIT_TEXT = "EDIT_TEXT"; 
    public static final String VALUES = "VALUES"; 


    private String[] mValues; 
    private NumberPicker numberPicker; 
    private EditText mEditText; 
    private String selectedValue; 

    private int lastAction = -1; 

    public EditTextDialogFragment() { 

    } 

    public static EditTextDialogFragment getNewInstance(EditText editText, String[] values) { 
     EditTextDialogFragment editTextDialogFragment = new EditTextDialogFragment(); 

     editTextDialogFragment.setValues(values); 
     editTextDialogFragment.setEditText(editText); 

     return editTextDialogFragment; 
    } 

    public void setEditText(EditText editText) { 
     mEditText = editText; 
    } 

    public void setValues(String[] values) { 
     mValues = values; 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setRetainInstance(true); 
    } 

    @Override 
    public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle savedInstanceState) { 

     View view = layoutInflater.inflate(R.layout.university_picker, viewGroup, false); 

     getDialog().getWindow().setGravity(Gravity.FILL_HORIZONTAL | Gravity.BOTTOM); 

     numberPicker = (NumberPicker) view.findViewById(R.id.numberPicker); 

     numberPicker.setMinValue(0); 

     selectedValue = (mValues.length == 0) ? "" : mValues[mValues.length/2]; 

     numberPicker.setMaxValue(mValues.length - 1); 

     numberPicker.setDisplayedValues(mValues); 

     numberPicker.setValue(mValues.length/2); 

     numberPicker.setWrapSelectorWheel(false); 

     numberPicker.setClickable(true); 

     numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() { 
      @Override 
      public void onValueChange(NumberPicker picker, int oldVal, int newVal) { 
       selectedValue = mValues[newVal]; 
      } 
     }); 


     numberPicker.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       boolean solution = false; 

       switch (event.getAction()) { 
        case (MotionEvent.ACTION_DOWN): 
         lastAction = MotionEvent.ACTION_DOWN; 
         solution = false; 
         break; 
        case (MotionEvent.ACTION_UP): 
         if (lastAction == MotionEvent.ACTION_DOWN) { 
          solution = true; 
         } 
         lastAction = MotionEvent.ACTION_UP; 
         break; 
        case (MotionEvent.ACTION_SCROLL): 
         lastAction = MotionEvent.ACTION_SCROLL; 
         solution = false; 
         break; 
        default: 
         lastAction = -1; 
         solution = false; 
         break; 
       } 

       if (solution) { 
        getDialog().dismiss(); 
        mEditText.setText(selectedValue); 
       } 

       return solution; 
      } 
     }); 

     return view; 
    } 
}
