android - requestWindowFeature(Window.FEATURE_NO_TITLE) exception
提问by aliosmeen
I am setting a specific activity full screen when the use hits a START button.
当用户点击开始按钮时，我正在全屏设置特定的活动。
In this case the showStopButton()is called .
在这种情况下，showStopButton()被称为 。
It's running fine. But if I insert
它运行良好。但是如果我插入
requestWindowFeature(Window.FEATURE_NO_TITLE);
then it crashes , stating that it should be call before adding content.
然后它崩溃了，说明应该在添加内容之前调用它。
How should I handle it to set NO_TITLEw the FULL_SCREEN??
我应该如何处理它来设置NO_TITLEw FULL_SCREEN??
private void showStopButton(){
// requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().findViewById(android.R.id.content).requestLayout();
// handle element visibility
((Button)findViewById(R.id.stopButton)).setEnabled(false);
((Button)findViewById(R.id.startButton)).setVisibility(View.GONE);
((Button)findViewById(R.id.stopButton)).setVisibility(View.VISIBLE);
((SeekBar)findViewById(R.id.seekBar1)).setVisibility(View.VISIBLE);
((Button)findViewById(R.id.resetButton)).setVisibility(View.GONE);
((Button)findViewById(R.id.saveButton)).setVisibility(View.GONE);
}
I have the reverse process when the START button is redisplayed , and it's running back fine In this case I remove the fullscreen mode
当重新显示 START 按钮时，我有相反的过程，并且它运行良好在这种情况下，我删除了全屏模式
private void showStartButton(){
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().findViewById(android.R.id.content).requestLayout();
....
}

So:
所以：
@Override
protected void onCreate(
final Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// Make this activity, full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Hide the Title bar of this activity screen
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
// MORE INIT STUFF HERE...
//img = (ImageView) findViewById(R.id.imgRandom);
//btnRandom = (Button) findViewById(R.id.btnRandom);
}

it's so simple ... I just need to hide the ActionBar... then show it when back to standard screen...
太简单了...我只需要隐藏ActionBar...然后在回到标准屏幕时显示它...
private void showStopButton(){
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
ActionBar actionBar = getActionBar();
actionBar.hide();
getWindow().findViewById(android.R.id.content).requestLayout();

Use -public class MainActivity extends Activity- instead of -public class MainActivity extends ActionBarActivity-
使用 -public class MainActivity extends Activity- 而不是 -public class MainActivity extends ActionBarActivity-
