Android之ViewFilpperGroup

ViewFilpperGroup顾名思义就是将一堆view添加到一组内，便于管理。

1、编写viewflipper.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <ViewFlipper        android:id="@+id/vf"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >    </ViewFlipper>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center_horizontal" >        <Button            android:id="@+id/up"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="up" />        <Button            android:id="@+id/auto"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="auto" />        <Button            android:id="@+id/next"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="next" />    </LinearLayout></LinearLayout>

2、编写first.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".FirstActivity" >    <TextView        android:id="@+id/txt1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/title_activity_first" /></RelativeLayout>

3、对应的Java代码

package org.zqy.andr;import android.os.Bundle;import android.app.Activity;import android.view.View;import android.view.View.OnClickListener;import android.widget.TextView;import android.widget.Toast;public class FirstActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_first);TextView txt1 = (TextView) findViewById(R.id.txt1);txt1.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Toast.makeText(getApplicationContext(), "hehe", Toast.LENGTH_SHORT).show();}});}}

 

4、编写seconde.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".SecondActivity" >    <TextView        android:id="@+id/txt2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/title_activity_second" /></RelativeLayout>

5、对应的Java代码

package org.zqy.andr;import android.os.Bundle;import android.app.Activity;import android.widget.TextView;public class SecondActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_second);TextView txt2 = (TextView) findViewById(R.id.txt2);}}

6、对应的Java代码

package org.zqy.andr;import android.os.Bundle;import android.app.ActivityGroup;import android.app.LocalActivityManager;import android.content.Intent;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.ViewFlipper;public class ViewFlipperGroupActivity extends ActivityGroup {private ViewFlipper vf;private Button up, auto, next;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.viewflipper2);vf = (ViewFlipper) findViewById(R.id.vf);//构建activitymanagerLocalActivityManager am =getLocalActivityManager();Intent intent1 = new Intent(ViewFlipperGroupActivity.this,FirstActivity.class);vf.addView(am.startActivity("activity1", intent1).getDecorView());//将Activity转换为viewIntent intent2 = new Intent(ViewFlipperGroupActivity.this,SecondActivity.class);vf.addView(am.startActivity("activity2", intent2).getDecorView());vf.startFlipping();//开始自动切换up = (Button) findViewById(R.id.up);auto = (Button) findViewById(R.id.auto);next = (Button) findViewById(R.id.next);up.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {vf.showPrevious();}});auto.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {vf.startFlipping();}});next.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {vf.showNext();}});}}
