Android基础：SlidingDrawer知识

SlidingDrawer抽屉，主要有handler和content组成，handler一般是图片，cotent随意，基本的方法主要有

open()、animateOpen()、close()、animateClose()、SlidingDrawer.setOnDrawerOpenListener()、SlidingDrawer.setOnDrawerCloseListener()

lock()、unlock(), 系统自带的抽屉可以从下往上、或者从右往左拉开，通过orientation来设置，如果要使SlidingDrawer按指定高度拉开，应该放到Relativelayout中，同时设置alignParentBotom为true.

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

    <SlidingDrawer
        android:id="@+id/slidingdrawer"
        android:layout_width="fill_parent"
        android:layout_height="400px"
        android:content="@+id/content"
        android:handle="@+id/handler"
        android:orientation="horizontal"
        android:layout_alignParentBottom="true" >

        <ImageView
            android:id="@id/handler"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/handler" />

        <TextView
            android:id="@+id/content"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:text="测试。。。。。。。。"
            android:textSize="18px"
            android:gravity="center_vertical"
            android:background="#ff00ff00" />
    </SlidingDrawer>

</RelativeLayout>

 

        handler = (ImageView) findViewById(R.id.handler);
        content = (TextView) findViewById(R.id.content);

        slidingdrawer.open();
        slidingdrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {

                ScaleAnimation anim = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f);
                anim.setDuration(1000);
//              slidingdrawer.setAnimation(anim);
//              slidingdrawer.startAnimation(anim);
                
            }
        });
