如何在點擊圖像時將與圖像關聯的字符串值分配給textwidget

Question

package com.me.trial; 

    import android.app.Activity; 
    import android.os.Bundle; 
    import android.view.View.OnClickListener; 
    import android.widget.ImageView; 

    public class TrialActivity extends Activity { 
     /** Called when the activity is first created. */ 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.main); 

      ImageView img = (ImageView)findViewById(R.id.imageView1); 

      img.setClickable(true); 
      OnClickListener l; 

     } 

     private void hasBeenClicked(<method invoked when the user has clicked>){ 


     } 
    } 






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

       android:layout_alignParentTop="true" 
       android:layout_marginLeft="56dp" 
       android:text="Large Text"

       <requestFocus /> 

      </EditText> 

      <ImageView 
       android:id="@+id/imageView1" 
       android:layout_width="match_parent"

       android:layout_alignParentLeft="true" 
       android:layout_alignParentTop="true" 
       android:scaleType="fitEnd" 
       android:tag="Employee name" 
       android:src="@drawable/img18" /> 




      </RelativeLayout> 
      </LinearLayout> 
</LinearLayout> 

我需要應用程序傳遞與它關聯的一些字符串值，以便在用戶點擊圖像後立即傳遞給文本如何在android中使用click Listener來實現以下任務。 沒有必要填寫我給出的代碼片段。任何關於設計的新想法都是最受歡迎的。

U可以設置文本爲Tag到圖像，以便您可以獲取該文本onClick事件。 Tag可以用XML或動態設置。

public class TrialActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     ImageView img = (ImageView)findViewById(R.id.imageView1); 
     img.setTag("YOur text"); 
     img.setClickable(true); 
     img.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
        String urText= arg0.getTag().toString(); 
        EditText edt = (EditText)findViewById(R.id.editText1); 
        edt.setText(urText); 
     } 
     });  
    } 
} 

此代碼演示如何動態地實現您的需求。
