我一直在关注 2 个教程，但都没有工作，我确保我添加了权限和依赖项。

这是我的代码：

      @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_get_location);

        mTextView = (TextView) findViewById(R.id.text);
        gps_loc = (TextView) findViewById(R.id.location);
        gps_btn = (Button) findViewById(R.id.gps_btn);
        next_act = (Button) findViewById(R.id.next_activity);

        fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);
        gps_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (Build.VERSION.SDK_INT >= 26) {
                    if (getApplicationContext().checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                        Toast.makeText(get_location.this, "Got Permission", Toast.LENGTH_SHORT).show();

                        fusedLocationProviderClient.getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {
                            @Override
                            public void onSuccess(Location location) {
                              if(location != null)
                              {
                                  Double lat = location.getLatitude();
                                  Double longt = location.getLongitude();
                                  gps_loc.setText(lat+","+longt);
                              }
                            }
                        });
                    }
                }
                else
                {
                    ActivityCompat.requestPermissions(get_location.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
                }

            }
        });
        next_act.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(get_location.this, circular_menu_external.class);
                startActivity(intent);
            }
        });

    }
}

我想了解在我制作的名为 gps_loc 的文本视图中显示 GPS 位置所必需的。

我拥有的智能手表是 Mobvoi 的 S2 TicWatch mad eby，是的，它确实包含 GPS 功能。我需要在我的 textView 中显示 GPS 等内容，但 GPS 位于我的列表顶部，但似乎没有任何效果。而且我不知道问题出在哪里或它是什么。

依赖项：

implementation 'com.google.android.gms:play-services-wearable:17.0.0'
implementation 'androidx.percentlayout:percentlayout:1.0.0'

implementation project(path: ':lvl_library')
implementation 'com.google.android.gms:play-services-location:18.0.0'
compileOnly 'com.google.android.wearable:wearable:2.8.1'

清单文件中的权限：

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