在支持Android Cupcake(1.5)的设备上,如何检查和激活GPS?


当前回答

此方法将使用LocationManager服务。

//Check GPS Status true/false
public static boolean checkGPSStatus(Context context){
    LocationManager manager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE );
    boolean statusOfGPS = manager.isProviderEnabled(LocationManager.GPS_PROVIDER);
    return statusOfGPS;
};

在Kotlin:如何检查GPS是否启用

 val manager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
        if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
            checkGPSEnable()
        } 

 private fun checkGPSEnable() {
        val dialogBuilder = AlertDialog.Builder(this)
        dialogBuilder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
                .setCancelable(false)
                .setPositiveButton("Yes", DialogInterface.OnClickListener { dialog, id
                    ->
                    startActivity(Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS))
                })
                .setNegativeButton("No", DialogInterface.OnClickListener { dialog, id ->
                    dialog.cancel()
                })
        val alert = dialogBuilder.create()
        alert.show()
    }

是的,你可以检查以下是代码:

public boolean isGPSEnabled (Context mContext){
    LocationManager locationManager = (LocationManager)
                mContext.getSystemService(Context.LOCATION_SERVICE);
    return locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}

在LocationListener中,实现onProviderEnabled和onProviderDisabled事件处理程序。当你调用requestLocationUpdates(…)时,如果手机上的GPS是禁用的,onProviderDisabled将被调用;如果用户启用GPS, onProviderEnabled将被调用。

下面是在我的情况下工作的片段

final LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE );
if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
    buildAlertMessageNoGps();
}

`

最好的方法似乎如下:

 final LocationManager manager = (LocationManager) getSystemService( Context.LOCATION_SERVICE );

    if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
        buildAlertMessageNoGps();
    }

  private void buildAlertMessageNoGps() {
    final AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Your GPS seems to be disabled, do you want to enable it?")
           .setCancelable(false)
           .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
               public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                   startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
               }
           })
           .setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                    dialog.cancel();
               }
           });
    final AlertDialog alert = builder.create();
    alert.show();
}
