WindowManager中的全屏

Question

这是我的代码：

params = new WindowManager.LayoutParams(
    WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.FLAG_FULLSCREEN,
    WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
    WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
    PixelFormat.TRANSLUCENT);

wm = (WindowManager) getApplicationContext()
    .getSystemService(Context.WINDOW_SERVICE);

inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mTopView = (ViewGroup) inflater.inflate(R.layout.activity_invisible, null);

params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
    | WindowManager.LayoutParams.FLAG_DIM_BEHIND
    | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
    | WindowManager.LayoutParams.FLAG_FULLSCREEN;

if (keep==true) {
    int value = brightnessIntent.getExtras().getInt("value");
    float v=value/255.0f;
    params.dimAmount=0;
    params.alpha=v;
    rl = (RelativeLayout) mTopView.findViewById(R.id.window);

    getWindow().setAttributes(params);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,

    WindowManager.LayoutParams.FLAG_FULLSCREEN);
    wm.addView(mTopView, params);
}

视图仍显示状态栏，mTopView是一个叠加窗口。如何让覆盖窗口覆盖整个屏幕？我不想“隐藏”状态栏，我希望我的活动叠加到它上面。

[编辑]强调文字我已经在我的onCreate()方法中有这个：

requestWindowFeature(Window.FEATURE_NO_TITLE); 
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

我的清单定义了一个全屏的风格。

这是目前的情况，我希望叠加层也扩展到状态栏。

Answer 1

我所要做的就是这个

params.flags=WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN| and the rest

这会将覆盖视图扩展到状态栏上。

此代码来自“Android Application 4 Development”。你必须处理不同的Android版本

 // Hiding the Action Bar for different android versions 
    if (Build.VERSION.SDK_INT < 16) {
        // Hide the Action Bar on Android 4.0 and Lower
         getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
     }else {
        // Hide the Action Bar on Android 4.1 and Higher
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
        android.app.ActionBar actionBar = getActionBar();
        actionBar.hide();
     }

Answer 3

您可以使用以下两种方式隐藏状态栏：

1）在您的活动onCreate()方法中定义以下行。

  requestWindowFeature(Window.FEATURE_NO_TITLE);

2）在应用程序级别定义主题，不要通过应用程序显示状态栏，如下所示：

<application android:label="@string/app_name"
  android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

Answer 4

试试这个..

   requestWindowFeature(Window.FEATURE_NO_TITLE);

它不会隐藏您的状态栏，您的应用程序将覆盖全屏仅显示状态栏

           public class example extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);


    setContentView(R.layout.example);
}

}

并隐藏状态栏

您可以使用

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

试试这种方式

final WindowManager.LayoutParams params = new WindowManager.LayoutParams( 
WindowManager.LayoutParams.FLAG_FULLSCREEN, 
WindowManager.LayoutParams.FLAG_FULLSCREEN,                 
            WindowManager.LayoutParams.TYPE_SYSTEM_ALERT,               
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
            PixelFormat.TRANSLUCENT);   

    WindowManager wm = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE);    

    ViewGroup mTopView = (ViewGroup) App.inflater.inflate(R.layout.main, null);
    getWindow().setAttributes(params);
    wm.addView(mTopView, params);

Answer 5

要在Android中创建始终如一的全屏叠加活动：

public void onCreate(Bundle savedInstanceState) {       
 super.onCreate(savedInstanceState);        

 requestWindowFeature(Window.FEATURE_NO_TITLE);
 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
 getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);             
 getWindow().setBackgroundDrawableResource(android.R.color.transparent);
 getWindow().setFormat(PixelFormat.TRANSLUCENT);
 setContentView(R.layout.main);
 }

必须在xml清单中外部启用半透明设置，否则它也不起作用。

 <item name="android:windowIsTranslucent">true</item>

您可以使用以下方法隐藏标题栏：

公共类MainActivity扩展AppCompatActivity {

@Override  
protected void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
    requestWindowFeature(Window.FEATURE_NO_TITLE);  
    getSupportActionBar().hide(); 
    setContentView(R.layout.activity_main);  


}  

}

并使用以下方式获取全屏：

公共类MainActivity扩展AppCompatActivity {

@Override  
protected void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    setContentView(R.layout.activity_main);  


}  

} 你也可以在styles.xml中使用parent =“Theme.AppCompat.NoActionBar”
