如何在android中禁用状态栏？

Question

我想在活动中禁用状态栏，我使用下面的代码，它发生 SecurityException， StatusBarManagerService：用户 10049 和当前进程都没有 android.permission.STATUS_BAR。我添加了<uses-permission android:name="android.permission.STATUS_BAR">，但它不起作用？有谁知道如何解决这个问题？谢谢

mStatusBar = getSystemService("statusbar");

if (mStatusBar != null){
    Log.v("statusbar", "get status bar service "+mStatusBar.getClass());
    Method[] arrayOfMethods;
    Method localMethod;
    arrayOfMethods = mStatusBar.getClass().getMethods();
    for (int i = 0; i < arrayOfMethods.length; i++){
        localMethod = arrayOfMethods[i];
        Log.v("statusbar", "find status bar method "+localMethod);
        if (localMethod.getName().equalsIgnoreCase("collapse")){
//                    mStatusBarCollapseMethod = localMethod;
            } else if (localMethod.getName().equals("disable")){
                try {
                    Log.v("statusbar", "invoke "+mStatusBar+"."+localMethod.getName()+"(1)");
                    localMethod.invoke(mStatusBar, 1);
                    Log.v("statusbar", "disable statusbar");
                } catch (Exception e) {
                    Log.v("statusbar", "disable statusbar excption:"+e.toString());
                    e.printStackTrace();
                }
            }
        }
    }
}

Answer 1

如果您需要从您的 java 代码中禁用状态栏，那么您可以这样做：

Window win = getWindow();
win.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 2

简单的解决方案，只需将android:theme=”@android:style/Theme.NoTitleBar.Fullscreen” 添加到您的清单中，例如：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="de.vogella.android.temperature"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Convert"
                  android:label="@string/app_name"
                   android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
    <uses-sdk android:minSdkVersion="9" />

</manifest>
