下面看代码：
package com.zhy.view;
import android.content.Context;
import android.support.v4.widget.SlidingPaneLayout;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
public class FoldSlidingPanelLayout extends SlidingPaneLayout
{
public FoldSlidingPanelLayout(Context context, AttributeSet attrs)
{
super(context, attrs);
}
@Override
protected void onAttachedToWindow()
{
super.onAttachedToWindow();
View child = getChildAt(0);
if (child != null) {
removeView(child);
final FoldLayout foldLayout = new FoldLayout(getContext());
//foldLayout.setAnchor(0);
foldLayout.addView(child);
ViewGroup.LayoutParams layPar = child.getLayoutParams();
addView(foldLayout, 0, layPar);
setPanelSlideListener(new PanelSlideListener()
{
@Override
public void onPanelSlide(View arg0, float arg1)
{
foldLayout.setFactor(arg1);
}
@Override
public void onPanelOpened(View arg0)
{
// TODO Auto-generated method stub
}
@Override
public void onPanelClosed(View arg0)
{
}
});
}
}
}
我们继承了SlidingPaneLayout，然后在onAttachedToWindow中，取出侧滑的布局，在外层包上一个FoldLayout；并且在内部去监听setPanelSlideListener，在onPanelSlide种根据参数，去动态设置FoldLayout的factor.
2、测试
（1）、布局文件
<com.zhy.view.FoldSlidingPanelLayout xmlns:android="http://www.easck.com/apk/res/android"
xmlns:tools="http://www.easck.com/tools"
android:id="@+id/id_drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="@+id/id_left_menu"
android:name="com.zhy.sample.folderlayout.LeftMenuFragment"
android:layout_width="240dp"
android:layout_height="match_parent" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitCenter"
android:src="@drawable/xueshan" />
</RelativeLayout>
</com.zhy.view.FoldSlidingPanelLayout>
