如何觸發廣播接收器在GPS開啟/關閉？

問題描述 投票：35回答：5

public class BootReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().matches("android.location.PROVIDERS_CHANGED")) {

Toast.makeText(context, "in android.location.PROVIDERS_CHANGED",

Toast.LENGTH_SHORT).show();

Intent pushIntent = new Intent(context, LocalService.class);

context.startService(pushIntent);

} else {

Toast.makeText(context, "not in android.location.PROVIDERS_CHANGED",

Toast.LENGTH_SHORT).show();

Intent pushIntent = new Intent(context, LocalService.class);

context.startService(pushIntent);

}

}

@Override

public void onLocationChanged(Location arg0) {

}

}

在我的應用程序，我需要觸發廣播接收器在GPS開啟/關閉。關注此事，并建議在應用程序以實現最好的一個。

android

gps

broadcastreceiver

location-provider

當用戶想觸發反過來任何行動開/關的位置提供，這是有用

你應該在清單中添加這個動作

并添加這個動作后，你可以觸發你的廣播接收器

而在你BroadcastReceiver類，你必須實現LocationListener在類，這是下面給出以下..

public class GpsLocationReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().matches("android.location.PROVIDERS_CHANGED")) {

Toast.makeText(context, "in android.location.PROVIDERS_CHANGED",

Toast.LENGTH_SHORT).show();

Intent pushIntent = new Intent(context, LocalService.class);

context.startService(pushIntent);

}

}

}

我想補充@Deepak古普塔answer。我想為當GPS狀態改變如何在您的片段或活動注冊一個動態brodacsast接收器添加代碼。

在您的活動或片段如下注冊您的廣播接收器。

private BroadcastReceiver gpsReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

if (intent.getAction().matches(LocationManager.PROVIDERS_CHANGED_ACTION)) {

//Do your stuff on GPS status change

}

}

};

對于片段：

getContext().registerReceiver(gpsReceiver, new IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION));

對于活動：

registerReceiver(gpsReceiver, new IntentFilter(LocationManager.PROVIDERS_CHANGED_ACTION));

這在使用，你必須訪問上下文，不只是一個活動或片段內的任何地方。我希望它的幫助。

你可以試試這個代碼，用戶@DanielNugent指出：

ContentResolver contentResolver = getContext().getContentResolver();

// Find out what the settings say about which providers are enabled

int mode = Settings.Secure.getInt(

contentResolver, Settings.Secure.LOCATION_MODE, Settings.Secure.LOCATION_MODE_OFF);

if (mode != Settings.Secure.LOCATION_MODE_OFF) {

if (mode == Settings.Secure.LOCATION_MODE_HIGH_ACCURACY) {

locationMode = "High accuracy. Uses GPS, Wi-Fi, and mobile networks to determine location";

} else if (mode == Settings.Secure.LOCATION_MODE_SENSORS_ONLY) {

locationMode = "Device only. Uses GPS to determine location";

} else if (mode == Settings.Secure.LOCATION_MODE_BATTERY_SAVING) {

locationMode = "Battery saving. Uses Wi-Fi and mobile networks to determine location";

}

}

后，Android定位模式工作的解決方案在Android中引入

我們可以使用位置模式檢查更精確

private boolean isGpsEnabled(Context context) {

ContentResolver contentResolver = getContext().getContentResolver();

// Find out what the settings say about which providers are enabled

// String locationMode = "Settings.Secure.LOCATION_MODE_OFF";

int mode = Settings.Secure.getInt(

contentResolver, Settings.Secure.LOCATION_MODE, Settings.Secure.LOCATION_MODE_OFF);

if (mode != Settings.Secure.LOCATION_MODE_OFF) {

return true;

/* if (mode == Settings.Secure.LOCATION_MODE_HIGH_ACCURACY) {

locationMode = "High accuracy. Uses GPS, Wi-Fi, and mobile networks to determine location";

} else if (mode == Settings.Secure.LOCATION_MODE_SENSORS_ONLY) {

locationMode = "Device only. Uses GPS to determine location";

} else if (mode == Settings.Secure.LOCATION_MODE_BATTERY_SAVING) {

locationMode = "Battery saving. Uses Wi-Fi and mobile networks to determine location";

}*/

} else {

return false;

}

}

你可以試試這個

表現

MyReceiver

if (intent.getAction().matches("android.location.GPS_ENABLED_CHANGE"))

{

boolean enabled = intent.getBooleanExtra("enabled",false);

Toast.makeText(context, "GPS : " + enabled,

Toast.LENGTH_SHORT).show();

}
