许可后的GPS位置不起作用（SDK 23）android studio

Question

我已经创建了这个类，我需要将我的最后一个位置放在哪里？

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)
            {

                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？ 在互联网上查看了许多示例，我已成功获取对话框以激活 GPS 设备，但是当我尝试获取位置时出现问题

Answer 1

当您想要连接到所提供的 Google API 之一时 在 Google Play 服务库（例如 Google 登录、游戏或 Drive），你需要创建一个 GoogleApiClient 的实例（“Google API 客户端”）。Google API 客户端为所有用户提供了一个通用入口点 Google Play 服务并管理两者之间的网络连接 用户的设备和每项 Google 服务。

• 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 在极少数情况下需要这样做。

将此添加到清单文件

<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>

在您的活动中添加此代码

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()));
        }
    }

在您的活动中的 onCreate 方法中
