如何在三星手机上使用以下来源显示选项菜单，但无法看到。如何解决？( )
try {
ViewConfigurationconfig = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if (menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
} catch (Exception e) {
e.printStackTrace();
}
startActivity(new Intent(Settings.ACTION_SETTINGS));
startActivity(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS));
startActivity(new Intent(Settings.ACTION_AIRPLANE_MODE_SETTINGS));
startActivity(new Intent(Settings.ACTION_BLUETOOTH_SETTINGS));
可能是由于 Android 操作系统内部问题，我们可以尝试重新安装操作系统并重新尝试工作
-AndroidManifest.xml <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />
都不对
