许可后 GPS 位置不起作用（SDK 23）android studio

Question

我有这个 class 我创建的，我需要把我最后的位置放在哪里？

public class DescriptionActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks {

    TextView t;
    Button up;
    GoogleApiClient mGoogleApiClient;
    LocationManager locationManager;
    LocationListener locationListener;
    LocationServices mLastLocation;
    private static final int PERMS_REQUEST_CODE=123;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hr__description);
        Toolbar toolbar = (Toolbar) findViewById(R.id.hr_toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_clear_white_24dp);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        t = (TextView) findViewById(R.id.test_boaz);
        up=(Button)findViewById(R.id.upload);
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(Drive.API)
                .addScope(Drive.SCOPE_FILE)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) this)
                .build();
        if(hasPermission())
        {
            getGPS();
        }
        else {
            requestPerms();
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case PERMS_REQUEST_CODE:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // All good!
                } else {
                   Log.d("bobbbbbbbbbbbbbbbbbb","boazboabzobaob");
                }

                break;
        }
    }

    private void getGPS() {
        up.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


            }
        });
    }

    private boolean hasPermission(){
            int res=0;
            String[] permissions=new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION};
            for(String params:permissions)
            {
                res=checkCallingOrSelfPermission(params);
                if(!(res==PackageManager.PERMISSION_GRANTED)) {
                    return false;
                }
            }
            return true;
        }

        private void requestPerms(){
            String[] permissions=new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION};
            if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
            {
             requestPermissions(permissions,PERMS_REQUEST_CODE);
                ActivityCompat.requestPermissions(this, permissions, PERMS_REQUEST_CODE);
            }

        }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onBackPressed();
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if (mLastLocation != null) {

        }
    }

    @Override
    public void onConnectionSuspended(int i) {

    }
}

我尝试激活 GPS，但它总是要我检查权限如何解决？查看了互联网上的许多示例，我成功地获得了激活 GPS 设备的对话框，但是当我尝试获取位置时，我遇到了问题

Answer 1

When you want to make a connection to one of the Google APIs provided in the Google Play services library (such as Google Sign-In, Games, or Drive), you need to create an instance of GoogleApiClient ("Google API Client"). The Google API Client provides a common entry point to all the Google Play services and manages the network connection between the user's device and each Google service.

自动管理您与 Google Play 服务的连接。
对任何 Google 执行同步和异步 API 调用播放服务。
手动管理您与 Google Play 服务的连接极少数情况下这是必要的。

Add this to manifest file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.google.android.gms.location.sample.basiclocationsample" >

  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
</manifest>

Add this code in your activity

mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Drive.API)
            .addScope(Drive.SCOPE_FILE)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build()
 @Override
    public void onConnected(Bundle connectionHint) {
        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
            mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
        }
    }
