android 控件onClick事件的4種實現方式

1、

		TextView tv = (TextView) findViewById(R.id.tv);
		tv.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				//do something...
			}
		});

2、

		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);
