Bug 修復

今天調試屏幕與視頻的同時旋轉測試出錯了：

其中AndroidManifest.xml：

<activity  android:name="com.starnet.DisplayOutput.TestRotate"
            android:configChanges="orientation|keyboardHidden|screenSize" >
</activity>

java旋轉方法：

class TestThread extends Thread{
        @Override  
        public void run() {           
int orientation = getRequestedOrientation();
System.out.println("____rotateflage   __"+orientation);
try{
Thread.currentThread();
Thread.sleep(1000);
}
catch(InterruptedException ie){}
if(pointer==4 && rotateflage){
if (orientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
else if(orientation == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
else if(orientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT )
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
else if(orientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE )
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
}
if(pointer==4 && rotateflage){
Message msgRo = new Message();    
if(countRotate<3){
msgRo.what=VEDIOROTATEOK;
}else {
msgRo.what = NESTOPTION3;
rotateflage=false;
}
TestRotate.this.myHandler.sendMessage(msgRo);  
}
}
    }

主要是myHandler發送 NESTOPTION3 消息去跳到下一個UI後出錯。

之後改爲：

class TestThread extends Thread{
        @Override  
        public void run() {           
int orientation = getRequestedOrientation();
System.out.println("____rotateflage   __"+orientation);
try{
Thread.currentThread();
Thread.sleep(1000);
}
catch(InterruptedException ie){}
if(pointer==4 && rotateflage){
if (orientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT)
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
else if(orientation == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
else if(orientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT )
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
else if(orientation == ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE )
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
}
try{
Thread.currentThread();
Thread.sleep(2000);
}
catch(InterruptedException ie){}
if(pointer==4 && rotateflage){
Message msgRo = new Message();    
if(countRotate<3){
msgRo.what=VEDIOROTATEOK;
}else {
msgRo.what=NESTOPTION3;
rotateflage=false;
}
TestRotate.this.myHandler.sendMessage(msgRo);
}
}
    }就OK無措了。

自己猜測是旋屏後馬上跳到別界面出錯，應該sleep會二再跳到其它UI。（菜鳥不要誤人子弟。我是菜鳥）
