Question

我在活动上有按钮，该按钮显示在片段上，只有显示的按钮，我做了搜索，并找出其渲染问题，但答案无效对我来说，此处外观如何。
片段活动

发布代码是否有可能位于按钮的空白处
Fragment.java

public class Smsar extends Fragment {


public Smsar() {
    // Required empty public constructor
}

View root;
Button mSmsar,mFinder;

 @Override
 public View onCreateView(LayoutInflater inflater, final ViewGroup container,
                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment
    root= inflater.inflate(R.layout.fragment_smsar, container, false);

    mSmsar=(Button)root.findViewById(R.id.smsar);
    mFinder=(Button)root.findViewById(R.id.finder);

    mSmsar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        getActivity().onBackPressed();
        }
    });
    mFinder.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            //Open Discover.

        }
    });



    return root;
 }
}

Answer 1

我通过用LinearLayout包围按钮来解决

<LinearLayout
    android:id="@+id/buttonContainer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/password"
    android:layout_marginTop="10dp"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
   >

    <Button
        android:id="@+id/logIn"
        android:layout_width="186dp"
        android:layout_height="wrap_content"
        android:layout_marginVertical="12dp"
        android:background="@drawable/btn_rounded"
        android:minWidth="200dp"
        android:onClick="logIN"
        android:text="@string/title_login"
        android:textAllCaps="false"
        android:textColor="@color/ms_white"
        android:textSize="18sp" />

</LinearLayout>

活动视图显示在片段上
