I think that you need to treat backevent as homeevent. The code below is how I emulate homepressed when User press backbutton:
我认为您需要将back事件视为home事件。下面的代码是我home在用户按下back按钮时模拟按下的方式：
public void minimizeApp() {
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);
}

try this code, this will minimize Activity.
试试这个代码，这将最小化活动。
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0)
{
this.moveTaskToBack(true);
return true;
}
return super.onKeyDown(keyCode, event);
}
or
或者
If you want to close the activity use this.finish()method to close the current running activity. instead of this.moveTaskToBack(true);
如果要关闭活动，请使用this.finish()方法关闭当前正在运行的活动。代替this.moveTaskToBack(true);
