本文实例讲述了Android编程单击图片实现切换效果的方法。分享给大家供大家参考，具体如下：

新建一个Android项目，命名为FrameLayout

此实例主要操作src文件夹下的MainActivity.Java类文件和res/layout下的activity_main.xml布局文件

1.布局主页面代码activity_main.xml↓

				?

									<FrameLayout

									xmlns:android="http://schemas.android.com/apk/res/android"

									android:layout_width="fill_parent"

									android:layout_height="fill_parent"

									android:background="#897753"

									>

									<ImageView

									android:id="@+id/image1"

									android:layout_width="fill_parent"

									android:layout_height="fill_parent"

									android:visibility="visible"

									android:src="@drawable/a"/>

									<ImageView

									android:id="@+id/image2"

									android:visibility="invisible"

									android:layout_width="fill_parent"

									android:layout_height="fill_parent"

									android:src="@drawable/b"/>

									<ImageView

									android:id="@+id/image3"

									android:visibility="invisible"

									android:layout_width="fill_parent"

									android:layout_height="fill_parent"

									android:src="@drawable/c"/>

									</FrameLayout>

2.Java代码MainActivity.Java↓

				?

									package com.example.framelayout;

									import java.util.ArrayList;

									import java.util.List;

									import android.app.Activity;

									import android.os.Bundle;

									import android.util.Log;

									import android.view.Menu;

									import android.view.MotionEvent;

									import android.view.View;

									import android.widget.ImageView;

									public class MainActivity extends Activity {

									private String TAG = "FramLayoutTestActivity";

									private ImageView image1;

									private ImageView image2;

									private ImageView image3;

									private List<ImageView> list;

									private int count = 0;

									@Override

									protected void onCreate(Bundle savedInstanceState) {

									super.onCreate(savedInstanceState);

									setContentView(R.layout.activity_main);

									image1 = (ImageView) findViewById(R.id.image1);

									image2 = (ImageView) findViewById(R.id.image2);

									image3 = (ImageView) findViewById(R.id.image3);

									list = new ArrayList<ImageView>();

									list.add(image1);

									list.add(image2);

									list.add(image3);

									}

									@Override

									public boolean onTouchEvent(MotionEvent event) {

									// TODO Auto-generated method stub

									if (event.getAction() == MotionEvent.ACTION_DOWN) {

									Log.i(TAG, "move---");

									showImage();

									}

									return super.onTouchEvent(event);

									}

									private void showImage() {

									//image1.setVisibility(View.VISIBLE);

									count = count % 3;

									for (ImageView i : list) {

									i.setVisibility(View.INVISIBLE);

									}

									list.get(count).setVisibility(View.VISIBLE);

									count++;

									}

									@Override

									public boolean onCreateOptionsMenu(Menu menu) {

									// Inflate the menu; this adds items to the action bar if it is present.

									getMenuInflater().inflate(R.menu.main, menu);

									return true;

									}

									}
