android 控件onClick事件的4种实现形式

<span style="white-space:pre">		</span>TextView tv = (TextView) findViewById(R.id.tv);		tv.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View arg0) {				// TODO Auto-generated method stub				//do something...			}		});

<span style="white-space:pre">		</span>TextView tv = (TextView) findViewById(R.id.tv);		OnClickListener mOnClickListener = new OnClickListener() {						@Override			public void onClick(View arg0) {				// TODO Auto-generated method stub				//do something...			}		};		tv.setOnClickListener(mOnClickListener);

package com.yqy.yqy_click;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.TextView;public class MainActivity extends Activity implements OnClickListener {	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		TextView tv = (TextView) findViewById(R.id.tv);		tv.setOnClickListener(this);	}	@Override	public void onClick(View view) {		// TODO Auto-generated method stub		switch (view.getId()) {		case R.id.tv:			//do something...			break;		default:			break;		}	}}

4、

<!-- android:clickable="true" 设置可点击权限 （ Button,ImageButton,等本身具有点击的事件的控件不用设置 ）-->    <TextView        android:id="@+id/tv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="onClick"        android:clickable="true"        android:text="@string/hello_world" />

<span style="white-space:pre">	</span>public void onClick(View view){		//do something...	}
