Android笔记之Button|Textiew设置监听

一、给Button设置监听

1、单个button

  Button buttontest;
  buttontest = (Button) findViewById(R.id.button1);
  buttontest.setOnClickListener(new View.OnClickListener() {    
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Log.i("TEST", "button onClick");
            }
        });

2、为多个按钮设置监听

(1)调用接口

public class NewText extends Activity  implements View.OnClickListener{
    private Button btn1,btn2;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_new_text);
        btn1=(Button)findViewById(R.id.button1);
                btn1.setOnClickListener(this);
        btn2=(Button)findViewById(R.id.button2);
                btn2.setOnClickListener(this);
    }
public void onClick(View v) {  
        switch (v.getId()) {  
        case R.id.button1:  
           //
            break;  
        case R.id.button2:  
           //
            break;  
        default:  
            break;  
        }  
    }

(2)不用调用接口

  { 
    /*....  */
    bt1.setOnClickListener(l);  
    bt2.setOnClickListener(l);  
    }  
      
    private OnClickListener l = new OnClickListener()  
    {  
        @Override  
        public void onClick(View v)  
        {  
            // TODO Auto-generated method stub  
            switch(v.getId())  
            {  
                case R.id.button1:  
                    //break;  
                case R.id.button2:  
                    //break;  
            }  
        }  
    };  

二、给TextView设置监听

{...
Title_Name.setClickable(true);
Title_Name.setFocusable(true);
Title_Name.setOnClickListener(l);
}
private OnClickListener l = new OnClickListener()  
    {  
        @Override  
        public void onClick(View v)  
        {          }  
    };
