Android事件分发详解(七)——将事件分发至特定的子View.

package cn.c;
import android.os.Bundle;
import android.app.Activity;
import android.view.MotionEvent;
import android.widget.Button;
/**
 * Demo描述:
 * 在MainActivity的dispatchTouchEvent方法中直接将事件指定给了MyButton
 * 比较简单,参见代码即可
 *
 * 备注说明:
 * 其他的代码和前几个例子一样,故不再贴出.

public class MainActivity extends Activity {
	private Button myButton;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        myButton=(Button) findViewById(R.id.button);
