Android的 - 4.2.2显示/隐藏系统栏(Nexus 10的)(Android - Sho

2019-08-17 05:12发布

我的问题与Nexus 10的 - 4.2.2。 我在下面的Galaxy Tab 10.1与4.0.4测试代码,它是很好的工作:

try 
{
    Process proc = Runtime.getRuntime().exec(new String[]{"sh","startservice","-n","com.android.systemui/.SystemUIService"});
    proc.waitFor();
} 
catch (Exception e) 
{
    e.printStackTrace();
}

try
{
    //REQUIRES ROOT
    Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 42 s16 com.android.systemui"}); //WAS 79
    proc.waitFor();
}
catch(Exception ex)
{
    //Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
}

但是Nexus 10的系统栏上之后不会显示,只是隐藏。

Answer 1:

为了显示和隐藏系统栏和通知栏4.2.2及其他:

隐藏:

    try
    {
        String command;
        command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib service call activity 42 s16 com.android.systemui";
        Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
        proc.waitFor();
    }
    catch(Exception ex)
    {
        Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
    }

节目:

    try 
    {
         String command;
         command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib am startservice -n com.android.systemui/.SystemUIService";
         Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
         proc.waitFor();
    } 
    catch (Exception e) 
    {
          e.printStackTrace();
    }


Answer 2:

我认为你不应该使用通过系统调用Runtime.exec()来获取结果。 你应该看看在代码FullscreenActivity模板(来源都放在<android-sdk-folder>/tools/templates/activities/FullscreenActivity/root ):这是显示如何显示/隐藏系统栏全工作示例(包括顶部和底部一个)程序,它甚至支持API 13+动画。



Answer 3:

通过goodm回答工作得很好,但我们大多数人都没有意识到有关envp

因此,这里是完整的代码:

隐藏

try
{
    String command;
    command = "LD_LIBRARY_PATH=/vendor/lib:/system/lib service call activity 42 s16 com.android.systemui";

    ArrayList<String> envlist = new ArrayList<String>();
    Map<String, String> env = System.getenv();
    for (String envName : env.keySet()) {
        envlist.add(envName + "=" + env.get(envName));
    }
    String[] envp = (String[]) envlist.toArray(new String[0]);
    Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command }, envp);
    proc.waitFor();
}
catch(Exception ex)
{
    Toast.makeText(getApplicationContext(), ex.getMessage(), Toast.LENGTH_LONG).show();
}

您可以使用显示出类似的。
