侧滑页面

**Android_app侧拉页面

一、直接上布局代码

<android.support.v4.widget.DrawerLayout
    android:id="@+id/draw"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#8CD3EC"
        android:orientation="horizontal">
        <Button
            android:id="@+id/btu"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="这是鬼"
            android:background="#BEE1"/>
    </LinearLayout>
    <!--=======================-分割线===========================-->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:background="#cccfff"
        android:orientation="horizontal">
        <Button
            android:id="@+id/btu2"
            android:text="这是鬼2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="#0A9B58"
           
    </LinearLayout>
</android.support.v4.widget.DrawerLayout>

二、Java代码

  DrawerLayout dra = findViewById(R.id.draw);
    //点击主页面中的按钮弹出侧滑页面
    dra.openDrawer(Gravity.LEFT);
    //点击侧滑页面中的按钮缩回侧滑页面
    dra.closeDrawer(Gravity.LEFT);
    //dra的侧拉监听事件
    dra.addDrawerListener(new DrawerLayout.DrawerListener() {
        @Override
        public void onDrawerSlide(@NonNull View view, float v) {

        }

        @Override
        public void onDrawerOpened(@NonNull View view) {
            Toast.makeText(MainActivity.this,"侧拉菜单打开",Toast.LENGTH_LONG).show();
        }

        @Override
        public void onDrawerClosed(@NonNull View view) {
            Toast.makeText(MainActivity.this,"侧拉菜单关闭",Toast.LENGTH_LONG).show();
        }

        @Override
        public void onDrawerStateChanged(int i) {
            Toast.makeText(MainActivity.this,"状态改变了",Toast.LENGTH_LONG).show();
        }
    });
