以编程方式打开GPS，如Ola Cabs Android应用程序 [英] Turn GPS on programmatically like Ola Cabs Android app
问题描述
我正在研究一个应用程序，需要集成GPS位置。我想以编程方式切换GPS。条件是：我不想将用户发送到设置面板以启用它。我想强制启用它或单个提示符将起作用（类似于Ola Cabs Android应用程序）。在这个网站上有很多这样的问题，但是每个人都在寻找类似于Ola Cabs应用程序的功能。所以我已经开始这个线程，以便我们所有人都可以清楚。
I am working on an application and need to integrate GPS location. I want to switch the GPS on programmatically. The condition is: I don't want to send the user to the Setting panel to enable it. I want to enable it forcefully or a single prompt will work (similar to the Ola Cabs Android app). A lot of questions are for this on this site but everyone is looking for the similar functionality like Ola Cabs app. So I have started this thread so that it can be clear for all of us.
推荐答案
这是我的100％工作代码，首先添加这个依赖 compile'com.google.android。 gms：play-services：9.2.1'到您的build.gradle（模块：应用程序）
Here is my 100% working code first add this dependencie compile 'com.google.android.gms:play-services:9.2.1' to your build.gradle(Module: app)
之后创建名称为 StartLocationAlert.java 并复制此代码并粘贴到此文件中。
After that create class with name StartLocationAlert.java and copy this code and paste in this file
import android.app.Activity;
import android.content.IntentSender;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;

import android.widget.Toast;
import com.example.googlemappromt.MainActivity;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.PendingResult;

public class StartLocationAlert implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

public StartLocationAlert(Activity context) {
this.context = context;

if(googleApiClient != null){
//googleApiClient.connect();

}
public GoogleApiClient getInstance(){
GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(context).addConnectionCallbacks(this).addOnConnectionFailedListener(this).addApi(LocationServices.API).build();
return mGoogleApiClient;
}
public void settingsrequest()
{
Log.e("settingsrequest","Comes");
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(30 * 1000);
locationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
builder.setAlwaysShow(true); //this is the key ingredient
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
// Log.e("Application","Button Clicked");
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
// Log.e("Application","Button Clicked1");
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(context, REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
Log.e("Applicationsett",e.toString());
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
//Log.e("Application","Button Clicked2");
Toast.makeText(context, "Location is Enabled", Toast.LENGTH_SHORT).show();
break;
}
}
});
}
@Override
public void onConnected(@Nullable Bundle bundle) {
/* MainActivity mm = new MainActivity();
mm.requestLocationUpdates();*/
Toast.makeText(context , "Connected", Toast.LENGTH_SHORT).show();
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
}
}
Usage of this above class is show below
@Override
protected void onResume() {
super.onResume();
Activity mContext = MainActivity.this //change this your activity name
StartLocationAlert startLocationAlert = new StartLocationAlert(mContext);
requestLocationUpdates();
}
不要忘记在 AndroidManifest.xml 文件，否则这可能无法正常工作
And don't forget to add below permissions in AndroidManifest.xml file or else this might not work properly
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
希望这可以帮到你..
Hope this might help you..
