看了这篇
模仿facebook布局效果还有这篇
仿朋友网左右两边可推出的菜单效果
感觉实现太复杂，自己又写过这篇
可左右两侧挤压傍边布局的Android抽屉，完全可以按照这个仿一个出来，简单又容易理解。
先看布局，布局很重要：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:id="@+id/layout_left"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@android:color/white"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
>
<!-- 这里添加其他控件，比如ListView -->
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="wwwwwwwwww"
android:textColor="@android:color/black"
/>
</LinearLayout>
<LinearLayout android:id="@+id/layout_right"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="@android:color/black"
android:layout_alignParentTop="true"
android:layout_marginLeft="280dip"
>
<ImageView android:id="@+id/iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher"
android:contentDescription="打开/关闭"
/>
<!-- 为了不让里面的控件出现“折叠”现象，所以给了个足够长的固定宽度 -->
<!-- 实际编程中该宽度最好计算求的 -->
<LinearLayout android:id="@+id/layout_max_width"
android:layout_width="300dip"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<!-- 这里添加其他控件，比如ListView -->
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="wwwwwwwwww"
android:textColor="@android:color/white"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="wwwwwwwwww"
android:textColor="@android:color/white"
/>
</LinearLayout>
</LinearLayout>
</RelativeLayout>
再看代码：
package com.dl.test;
import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.ViewTreeObserver;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.RelativeLayout.LayoutParams;
public class App extends Activity implements OnPanelStatusChangedListener{
private boolean hasMeasured=false;
private LinearLayout layout_left;
private LinearLayout layout_right;
private ImageView iv;
private LayoutParams lp;
private int layout_left_width,layout_right_width=0;
/**每次自动展开/收缩的范围*/
private int MAX_WIDTH=0;
/**每次自动展开/收缩的速度*/
private final static int SPEED=20;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
layout_left=(LinearLayout)findViewById(R.id.layout_left);
layout_right=(LinearLayout)findViewById(R.id.layout_right);
iv=(ImageView)findViewById(R.id.iv);
iv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
LayoutParams lp = (android.widget.RelativeLayout.LayoutParams)layout_right.getLayoutParams();
if (lp.leftMargin >=MAX_WIDTH)// CLOSE的状态
new AsynMove().execute(new Integer[] { -SPEED });// 负数展开
else if (lp.leftMargin >= 0)// OPEN的状态
new AsynMove().execute(new Integer[] { SPEED });// 正数收缩
}
});
ViewTreeObserver observer = layout_right.getViewTreeObserver();
// observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
// @Override
// public void onGlobalLayout() {
// if (hasMeasured == false){
// layout_right_width = layout_right.getMeasuredWidth();//105
// layout_left_width=layout_left.getMeasuredWidth();//480
// MAX_WIDTH=layout_left_width-layout_right_width;//375
// hasMeasured = true;
// }
// }
// });
//为了取得控件的宽
observer.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener(){
public boolean onPreDraw(){
if (hasMeasured == false){
layout_right_width = layout_right.getMeasuredWidth();
layout_left_width=layout_left.getMeasuredWidth();
MAX_WIDTH=layout_left_width-layout_right_width;
// Log.i("tag", "MAX_WIDTH=="+MAX_WIDTH);
hasMeasured = true;
//设置可拉动容器的宽为全屏（即不可拉动容器）的宽
View layout_max_width=findViewById(R.id.layout_max_width);
LinearLayout.LayoutParams lp=(LinearLayout.LayoutParams)layout_max_width.getLayoutParams();
lp.width=layout_left_width;
layout_max_width.setLayoutParams(lp);
}
return true;
}
});
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
}
@Override
public void onAttachedToWindow() {
// TODO Auto-generated method stub
super.onAttachedToWindow();
}
class AsynMove extends AsyncTask<Integer, Integer, Void> {
@Override
protected Void doInBackground(Integer... params) {
int times;
if (MAX_WIDTH % Math.abs(params[0]) == 0)// 整除
times = MAX_WIDTH / Math.abs(params[0]);
else
times = MAX_WIDTH / Math.abs(params[0]) + 1;// 有余数
for (int i = 0; i < times; i++) {
publishProgress(params);
try {
Thread.sleep(Math.abs(params[0]));
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return null;
}
@Override
protected void onProgressUpdate(Integer... params) {
LayoutParams lp = (LayoutParams)layout_right.getLayoutParams();
if (params[0] < 0)
lp.leftMargin = Math.max(lp.leftMargin + params[0], 0);
else
lp.leftMargin = Math.min(lp.leftMargin + params[0], MAX_WIDTH);
if(lp.leftMargin<=0){//展开之后
onPanelOpened();//调用OPEN回调函数
}
else if(lp.leftMargin>=MAX_WIDTH){//收缩之后
onPanelClosed();//调用CLOSE回调函数
}
layout_right.setLayoutParams(lp);
}
}
@Override
public void onPanelOpened() {
// TODO Auto-generated method stub
Log.i("tag", "=========onPanelOpened========");
}
@Override
public void onPanelClosed() {
// TODO Auto-generated method stub
Log.i("tag", "=========onPanelClosed========");
}
}
接口：
package com.dl.test;
public interface OnPanelStatusChangedListener {
void onPanelOpened();
void onPanelClosed();
}
打开前：
打开后：
这样设计有一点不好，就是所有的代码都需要写在一个activity中，代码多了会很臃肿。
小米测试通过。
