检查是否有网络/飞机模式活动

Question

我有一个使用Google platpicker和Google StreetView的应用程序。我必须在飞机模式下使用设备测试应用程序。

我希望该应用程序在飞机模式处于活动状态时检查何时到达此活动，如果它不活动，我希望显示Toast

以下是活动的活动的代码，其中有2个按钮，其中一个按钮加载了安慰剂，另一个按钮加载了另一个包含StreetView的活动。

我已经看到了这一点，一个人如何在Android上检测飞机模式？答案，这就是我在答案中尝试的代码的地方，但它不会可行

有人可以告诉我如何使此工作

public class PlacePickerActivity extends AppCompatActivity {
int PLACE_PICKER_REQUEST = 1;
TextView tvPlace;
private Button buttonStepsActivity;
private Button buttonStreet;
private boolean isAirplaneModeOn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_place_picker);
tvPlace = (TextView)findViewById(R.id.tvPlace);
//StreetView
buttonStreet =  (Button) findViewById(R.id.buttonStreet);
if(isAirplaneModeOn) {
    Toast.makeText(this,"Aeroplane mode active",Toast.LENGTH_LONG).show();
}
}
private static boolean isAirplaneModeOn(Context context) {
return Settings.System.getInt(context.getContentResolver(),
        Settings.System.AIRPLANE_MODE_ON, 0) != 0;
}

public void goPlacePicker(View v) {
// Construct an intent for the place picker
try {
    PlacePicker.IntentBuilder intentBuilder =
            new PlacePicker.IntentBuilder();
    Intent intent = intentBuilder.build(this);
    // Start the intent by requesting a result,
    // identified by a request code.
    startActivityForResult(intentBuilder.build(this), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException e) {
    e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
    e.printStackTrace();
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
    if (resultCode == RESULT_OK) {
        Place place = PlacePicker.getPlace(data, this);
        String toastMsg = String.format("You have chosen: %s", place.getName());
        Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
    }
}
}

使用这种方式

查找网络启用

    public static boolean isNetworkAvailable(Context mContext) {
    ConnectivityManager connectivity = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
    if (connectivity != null) {
        NetworkInfo[] info = connectivity.getAllNetworkInfo();
        if (info != null) {
            for (int i = 0; i < info.length; i++) {
                if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                    return true;
                }
            }
        }
    }
    return false;
}

查找飞机模式启用

private static boolean isAirplaneModeOn(Context context) {
return Settings.System.getInt(context.getContentResolver(),
       Settings.System.AIRPLANE_MODE_ON, 0) != 0;
}
