Button 的onclicklistener 常用方法之嵌套内部类

   1:  package com.yang.huang;

   2:   

   4:  import android.app.Activity;

   5:  import android.os.Bundle;

   6:  import android.view.View;

   7:  import android.widget.Button;

   8:  import android.widget.TextView;

   9:   

  10:  public class TestonlistenerActivity extends Activity{

  11:      TextView tv;

  12:      Button button;

  13:      /** Called when the activity is first created. */

  14:      @Override

  15:      public void onCreate(Bundle savedInstanceState) {

  16:          super.onCreate(savedInstanceState);

  17:          setContentView(R.layout.main);

  18:          

  19:          button=(Button)findViewById(R.id.button1);

  20:          tv = (TextView)findViewById(R.id.textView1);

  21:          

  22:          button.setOnClickListener( {

  23:              

  24:              public void onClick(View v) {

  25:                  // TODO Auto-generated method stub

  26:                  tv.setText("单击就会改变textview里的文字");

  27:              }

  28:          });

  29:         

  30:      }

  31:   }

这种不需要实现onclicklistener接口，直接使用嵌套内部类。即可完成添加Button的单击事件。
