java - Android Settings.ACTION_DISPLAY_SETTINGS 未找到

Question

我想在我的 Activity 中调整显示设置。

Intent intent=new Intent(Settings.ACTION_DISPLAY_SETTINGS);             startActivity(intent);

but i am getting following exception:

09-24 21:24:35.901: ERROR/AndroidRuntime(5892): 
android.content.ActivityNotFoundException: 
    No Activity found to handle Intent 
        { action=android.settings.DISPLAY_SETTINGS }

Answer 1

你应该:

try {
    final Intent i = new Intent(Settings.ACTION_DISPLAY_SETTINGS);
    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // not sure if needed
    startActivity(i);
} catch (ActivityNotFoundException e) {
    // not much you can do
}
