侧滑界面的实现

侧滑界面——向右滑动或者是点击左上角的一个文本进行侧滑

主界面activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="10dp"
    android:id="@+id/drawerLayout"
    tools:context=".MainActivity">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginLeft="10dp">

        <TextView
            android:id="@+id/slide_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="侧滑"
            android:layout_marginTop="10dp"
            android:textSize="15sp"
            android:textColor="#000000"
            />

    </RelativeLayout>

    <!--侧滑界面,必须设置layout_gravity属性,表示侧滑方向-->
    <RelativeLayout
        android:layout_gravity="start"
        android:id="@+id/ll"
        android:background="#FFFF00"
        android:orientation="vertical"
        android:layout_width="300dp"
        android:layout_height="match_parent">

        <Button
            android:id="@+id/btn_add"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="添加账户"
            android:layout_marginTop="20dp"
            android:background="#1E86FD"
            />

    </RelativeLayout>

</androidx.drawerlayout.widget.DrawerLayout>

 MainActivity.java

public class MainActivity extends AppCompatActivity{
    //侧滑
    private TextView mSlideName;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //侧滑
        final DrawerLayout drawerLayout=findViewById(R.id.drawerLayout);
        //给按钮添加一个监听器
        mSlideName=findViewById(R.id.slide_name);
        Intent intent = getIntent();
        mSlideName.setText(intent.getStringExtra("user_name"));
        mSlideName.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //打开侧滑菜单
                drawerLayout.openDrawer(GravityCompat.START);
            }
        });
    }
}    

以上便是完成侧滑的相应步骤
