Toast字符串顯示對象而不是文本

Question

在我的代碼中，我想顯示TextView文本名稱作爲Toa​​st消息。 我做了以下編碼。我沒有得到我得到的文本的唯一對象。

在吐司我想顯示文本，請指導我如果可能的話。 這裏是我的代碼：

package com.Viewflipper; 

    import android.app.Activity; 
    import android.os.Bundle; 
    import android.view.View; 
    import android.view.View.OnClickListener; 
    import android.widget.Button; 
    import android.widget.Toast; 
    import android.widget.ViewFlipper; 

    public class Viewflipper extends Activity implements OnClickListener { 
     /** Called when the activity is first created. */ 
     Button next; 
     Button previous; 
     ViewFlipper vf; 

     /** Called when the activity is first created. */ 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       setContentView(R.layout.main); 
       vf = (ViewFlipper) findViewById(R.id.ViewFlipper01); 
       next = (Button) findViewById(R.id.Button01); 
       previous = (Button) findViewById(R.id.Button02); 
       next.setOnClickListener(this); 
       previous.setOnClickListener(this); 
     } 

     @Override 
     public void onClick(View v) { 
       // TODO Auto-generated method stub 
       if (v == next) { 
         vf.showNext(); 
         Toast.makeText(this,vf.toString(), Toast.LENGTH_SHORT).show(); 

         **//HERE I DIDN'T GET vf.getText().toString();** 

       } 
       if (v == previous) { 
         vf.showPrevious(); 
       } 
     } 
    } 

**EDITED** 


main.xml 


<?xml version="1.0" encoding="utf-8"?>

試試這個： -

package com.Viewflipper; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.Toast; 
import android.widget.ViewFlipper; 

public class Viewflipper extends Activity implements OnClickListener { 
    /** Called when the activity is first created. */ 
    Button next; 
    Button previous; 
    ViewFlipper vf; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 
      vf = (ViewFlipper) findViewById(R.id.ViewFlipper01); 
      next = (Button) findViewById(R.id.Button01); 
      previous = (Button) findViewById(R.id.Button02); 
      next.setOnClickListener(this); 
      previous.setOnClickListener(this); 
    } 

    @Override 
    public void onClick(View v) { 
      // TODO Auto-generated method stub 
      if (v == next) { 
         vf.showNext(); 
        Toast.makeText(getApplicationContext(),((TextView) vf.getCurrentView()).getText(), Toast.LENGTH_SHORT).show(); 


      } 
      if (v == previous) { 
        vf.showPrevious(); 
      } 
    } 
} 

要顯示的文字

一個ViewFliper是一個適配器..你不能抓住它這樣，你必須與適配器互動，並獲得視圖和THEN搶在TextView的視圖。
