Android实现抽屉样式

1：布局文件

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   <LinearLayout
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="vertical">

      <Button
          android:id="@+id/btn_drawer"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="打开抽屉" />
   </LinearLayout>

   <!--这是侧边栏滑动时出现的右边布局内容-->
   <LinearLayout
       android:id="@+id/drawer_content"
       android:layout_width="280dp"
       android:layout_height="match_parent"
       android:layout_gravity="end" 抽屉向左展示则改为start即可
       android:clickable="true"
       android:orientation="vertical"
       android:background="#fff">

      <TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:padding="10dp"
          android:text="嗯嗯"
          android:textStyle="bold" />

      <TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:padding="10dp"
          android:text="喜喜"
          android:textStyle="bold" />

      <View
          android:layout_width="0dp"
          android:layout_height="0dp"
          android:layout_weight="1" />

      <TextView
          android:id="@+id/processed_commit"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:gravity="center"
          android:padding="10dp"
          android:text="完成"
          android:textSize="16sp" />
   </LinearLayout>
</androidx.drawerlayout.widget.DrawerLayout>

2：主要代码

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private DrawerLayout mDrawerLayout;
    private LinearLayout drawer_content;
    private GridView stateGV;
    private GridView timeGV;
    private TextView filterTV;
    private Button btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer_content = (LinearLayout) findViewById(R.id.drawer_content);
        filterTV = (TextView) findViewById(R.id.processed_commit);
        btn = (Button) findViewById(R.id.btn_drawer);

        filterTV.setOnClickListener(this);
        btn.setOnClickListener(this);
        mDrawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
            }

            @Override
            public void onDrawerOpened(View drawerView) {
                mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
            }

            @Override
            public void onDrawerClosed(View drawerView) {
                mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
            }

            @Override
            public void onDrawerStateChanged(int newState) {
            }
        });
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.processed_commit:
                mDrawerLayout.closeDrawers();
                break;
            case R.id.btn_drawer:
                mDrawerLayout.openDrawer(drawer_content);
                break;
        }
    }
