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();
}
