Android(安卓)Fragment

fragment的使用
新建FineTuningModeFragment

public class FineTuningModeFragment extends Fragment {         @Nullable    @Override    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {             View view = inflater.inflate(R.layout.fine_tuning_mode_layout, container, false);        return view;    }}

新建fine_tuning_mode_layout

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <TextView        android:text="weitiao"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/></LinearLayout>

使用

<fragment    android:id="@+id/fine_tuning_mode_fragment"    android:name="com.example.mydemo.hydraumaticrisetower.Fragment.RiseTowerModeFragment"    android:layout_width="wrap_content"    android:layout_height="wrap_content"/>

两个fragment切换
再新建RiseTowerModeFragment

public class RiseTowerModeFragment extends Fragment {         @Nullable    @Override    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {             View view = inflater.inflate(R.layout.rise_tower_mode_layout, container, false);        return view;    }}

新建rise_tower_mode_layout.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <TextView        android:text="shenta"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/></LinearLayout>

使用
1.

将<fragment    android:id="@+id/fine_tuning_mode_fragment"    android:name="com.example.mydemo.hydraumaticrisetower.Fragment.RiseTowerModeFragment"    android:layout_width="wrap_content"    android:layout_height="wrap_content"/>改为<FrameLayout    android:id="@+id/framelayout"    android:layout_width="match_parent"    android:layout_height="wrap_content"/>

activity新增

private void replaceFragment(Fragment fragment) {         FragmentManager fragmentManager = getSupportFragmentManager();    FragmentTransaction transaction = fragmentManager.beginTransaction();    transaction.replace(R.id.framelayout, fragment);    transaction.commit();}使用replaceFragment(new RiseTowerModeFragment());和replaceFragment(new FineTuningModeFragment());切换
