VideoView大小屏幕切换的总结

最近做一个app要用到视频的播放，毫无疑问的选择了VieoView，但是在使用的时候发现VideoView全屏的时候还是有些学问的。。。先不管那么多了，把可以实现全屏与指定大小页面的效果的解决方案记录下来好了。。。

步骤1：

自定义一个VideoView,重写里面的onMeasure

package com.jone.jonevideo.widget;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class MyVideoView extends VideoView {

public MyVideoView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

public MyVideoView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public MyVideoView(Context context) {
super(context);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// TODO Auto-generated method stub

int width = getDefaultSize(0, widthMeasureSpec);
int height = getDefaultSize(0, heightMeasureSpec);
setMeasuredDimension(width, height);
}

}

步骤2： 用一个布局来包裹你的VideoView [以后我们会在代码中控制VideoView的父布局来实现切换大小]

<FrameLayout 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:orientation="vertical" >

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >

<com.jone.jonevideo.widget.MyVideoView
android:id="@+id/audtoView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" >

<Button
android:id="@+id/audio_start"
style="@style/layout_wrap_content"
android:text="start_audio" />

<Button
android:id="@+id/audio_2_video"
style="@style/layout_wrap_content"
android:text="@string/switch_audio_2_vidwo" />

<Button
android:id="@+id/entry_list_audio"
style="@style/layout_wrap_content"
android:text="@string/entry_audio_list" />
</LinearLayout>

</FrameLayout>

步骤3： 通过代码来设置全屏与否的切换

if(!fullscreen){//设置RelativeLayout的全屏模式
RelativeLayout.LayoutParams layoutParams=
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
mVideoView01.setLayoutParams(layoutParams);

fullscreen = true;//改变全屏/窗口的标记
}else{//设置RelativeLayout的窗口模式
RelativeLayout.LayoutParams lp=new  RelativeLayout.LayoutParams(320,240);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
mVideoView01.setLayoutParams(lp);
fullscreen = false;//改变全屏/窗口的标记
}

完事搞定
