混淆了将这些代码实现到Fragment.java 您能否从Activity到Fragment实施这些代码？我要设置自动更新位置，然后单击“提取”按钮来显示地址。
我有这些MainActivity.java代码，我想将它们实现到Fragment.java，但我不知道该怎么做。

对于Activity，您将使用AppCompact活动进行扩展。同样，您需要使用Fragment来扩展fragment。
对于context，无论您在何处使用“ this”，都应将其替换为“ getActivity（）”或“ getContext（）”。
Fragment有一个名为onCreateView（LayoutInflater，ViewGroup，Bundle）的方法。覆盖它，使用布局填充并返回视图。
膨胀您在onCreateView中查看的位置，例如：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.activity_main, container, false);
}
在fragment的Override方法onViewCreate（）方法中调用方法的其余部分。否则，您可以在onActivityCreated（Bundle savedInstanceState）方法中调用这些方法。
在onViewCreate中调用这些方法：
requestMultiplePermissions();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
// mLocationManager = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
checkLocation();
textView = findViewById(R.id.tv);
tvCountry = findViewById(R.id.tvCountry);
tvState = findViewById(R.id.tvState);
tvCity = findViewById(R.id.tvCity);
tvPincode = findViewById(R.id.tvPincode);
tvFeature = findViewById(R.id.tvFeature);
btn = findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
setAddress(latitude,longitude);
}
});
