准备一张名为picture的图片。
在main.xml中：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#3399ff">
<ImageView
android:id="@+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/picture"/>
</LinearLayout>
在MyMultitouchDemo.java中：
package com.li.multitouch;
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
public class MyMultitouchDemo extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.main);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
System.out.println("获得两点的坐标");
if (event.getPointerCount() == 2) {
System.out.println("坐标A：X = " + event.getX(0) + "，Y = "
+ event.getY(0));
System.out.println("坐标B：X = " + event.getX(1) + "，Y = "
+ event.getY(1));
}
return super.onTouchEvent(event);
}
}
