我已经编写了某些代码，这样我的 android 应用程序应该进入飞行模式并在一段时间内回到网络连接模式，直到我强行关闭应用程序。它使用我编写的代码，但问题是屏幕或显示器没有显示飞行符号。当我进入设置时，我可以看到代码正在正确启用和禁用飞行模式。
任何人都可以给我一个解决方案。
我的代码如下
public class Airplane_ModeActivity extends Activity implements Runnable{
private static final int SLEEP_TIME_VALUE = 10000;
private static Context context;
private static ContentResolver contentResolver;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
context = getApplicationContext();
contentResolver = context.getContentResolver();
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", false);
sendBroadcast(intent);
Runnable runnable = new Airplane_ModeActivity();
Thread thread = new Thread(runnable);
thread.start();
}
public void run(){
while(true) {
while(0==Settings.System.getInt(contentResolver, Settings.System.AIRPLANE_MODE_ON, 0) ) {
Settings.System.putInt(contentResolver, Settings.System.AIRPLANE_MODE_ON, 1);
try {
Thread.sleep(SLEEP_TIME_VALUE);
}
catch (InterruptedException ie) {
}
}
try {
Thread.sleep(SLEEP_TIME_VALUE);
}
catch (InterruptedException ie) {
}
while(1==Settings.System.getInt(contentResolver, Settings.System.AIRPLANE_MODE_ON, 1) ) {
Settings.System.putInt(contentResolver, Settings.System.AIRPLANE_MODE_ON, 0);
try {
Thread.sleep(SLEEP_TIME_VALUE);
}
catch (InterruptedException ie) {
}
}
try {
Thread.sleep(SLEEP_TIME_VALUE);
}
catch (InterruptedException ie) {
}
}
}
}
