Android11 桌面默认横屏导致任务键近期任务布局UI显示错误！

/frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java

定义变量：private boolean stch = false;

keyCode == KeyEvent.KEYCODE_APP_SWITCH

取消原来逻辑，采用广播打开近期任务后台

/*/
if (!keyguardOn) {
if (down && repeatCount == 0) {
preloadRecentApps();
} else if (!down) {
toggleRecentApps();
}
}
//*/

新增代码如下：

//*/if (down) {stch = !stch;if (stch) {Intent intent = new Intent();intent.setClassName("com.android.launcher3","com.android.quickstep.RecentsActivity");intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP );Log.d("TYD","---------RecentsActivity-------------"+intent);mContext.startActivity(intent);stch = true;} else {//mGotoBack();if("com.android.launcher3.uioverrides.QuickstepLauncher".equals(getCurrentActivityName()) ) {Intent intent2 = new Intent();intent2.setClassName("com.android.launcher3","com.android.quickstep.RecentsActivity");intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP );Log.d("TYD","---------RecentsActivity222-------------"+intent2);mContext.startActivity(intent2);stch = true;Log.d("TYD","---------else stch:-------------"+stch);} else {mGotoEnter();mGotoEnter2();Log.d("TYD","---------mGotoEnter-------------"+stch);}}}//*/

引用模拟按键方法：

广播open两次+打开应用需确认两次。目前验证暂无其他bug。

//*/update recents app layout +QuickstepLauncher
   private void mGotoBack(){
new Thread() {
       public void run() {
       try {
       Instrumentation inst = new Instrumentation();
       inst.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);
       } catch (Exception e) {
       e.printStackTrace();
       }
       }
       }.start();
}
private void mGotoEnter(){
new Thread() {
       public void run() {
       try {
       Instrumentation inst = new Instrumentation();
       inst.sendKeyDownUpSync(KeyEvent.KEYCODE_DPAD_CENTER);//KEYCODE_DPAD_CENTER //KEYCODE_ENTER
       } catch (Exception e) {
       e.printStackTrace();
       }
       }
       }.start();
}
private void mGotoEnter2(){
new Thread() {
       public void run() {
       try {
       Instrumentation inst = new Instrumentation();
       inst.sendKeyDownUpSync(KeyEvent.KEYCODE_DPAD_CENTER);//KEYCODE_DPAD_CENTER //KEYCODE_ENTER
       } catch (Exception e) {
       e.printStackTrace();
       }
       }
       }.start();
}
