android中的OnClickListener两种实现方式

android的activity点击事件中,通过OnClickListener来实现,要实现点击事件有两种方式

1、通过定义一个OnClickListener的内部类来实现

The example below shows how to register an on-click listener for a Button.
// Create an anonymous implementation of OnClickListener
private OnClickListener mCorkyListener = new OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
}
}; protected void onCreate(Bundle savedValues) {
...
// Capture our button from layout
Button button = (Button)findViewById(R.id.corky);
// Register the onClick listener with the implementation above
button.setOnClickListener(mCorkyListener);
...
}

  

2、通过实现View.OnClickListener接口来实现

public class ExampleActivity extends Activity implements OnClickListener {
protected void onCreate(Bundle savedValues) {
...
Button button = (Button)findViewById(R.id.corky);
button.setOnClickListener(this);
} // Implement the OnClickListener callback
public void onClick(View v) {
// do something when the button is clicked
}
}
