用於設計Android中的動態佈局，如主屏幕中的狀態欄

Question

如何在Android中進行佈局，如主屏幕中的狀態欄，允許用戶將狀態欄拖動到任意高度。佈局還應該允許用戶向上或向下輕彈以充分展開或縮小布局。

你的意思是類似SlidingDrawer？

可以使用這樣的：

/src目錄 - SliderActivity.java：

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.Button; 
import android.widget.SlidingDrawer; 
import android.widget.SlidingDrawer.OnDrawerCloseListener; 
import android.widget.SlidingDrawer.OnDrawerOpenListener; 

public class SliderActivity extends Activity { 
    Button slideHandleButton; 
    SlidingDrawer slidingDrawer; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setContentView(R.layout.main); 
     slideHandleButton = (Button) findViewById(R.id.slideHandleButton); 
     slidingDrawer = (SlidingDrawer) findViewById(R.id.SlidingDrawer); 

     slidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() { 
      @Override 
      public void onDrawerOpened() { 
       slideHandleButton.setBackgroundResource(R.drawable.arrowdown); 
      } 
     }); 

     slidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() { 
      @Override 
      public void onDrawerClosed() { 
       slideHandleButton.setBackgroundResource(R.drawable.arrowup); 
      } 
     }); 
    } 
} 

/RES /佈局 - main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout android:id="@+id/LinearLayout01" 
    android:layout_width="fill_parent" android:layout_height="fill_parent" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:gravity="bottom"> 
    <SlidingDrawer android:layout_width="wrap_content" 
     android:id="@+id/SlidingDrawer" android:handle="@+id/slideHandleButton" 
     android:content="@+id/contentLayout" android:padding="10dip" 
     android:layout_height="200dip"> 
     <Button android:layout_width="wrap_content" 
      android:layout_height="wrap_content" android:id="@+id/slideHandleButton" 
      android:background="@drawable/arrowup"></Button> 
     <LinearLayout android:layout_width="wrap_content" 
      android:id="@+id/contentLayout" android:orientation="vertical" 
      android:gravity="center|top" android:padding="10dip" 
      android:background="#505050" android:layout_height="wrap_content"> 
      <TextView android:id="@+id/TextView01" android:layout_width="wrap_content" 
       android:layout_height="fill_parent" android:layout_weight="8" android:text="Hello Slider"></TextView> 
      <Button android:id="@+id/Button02" android:layout_weight="2" android:layout_width="wrap_content" 
       android:layout_height="wrap_content" android:text="Do anything"></Button> 
     </LinearLayout> 
    </SlidingDrawer> 
</LinearLayout> 

你需要在你的/ RES 2個圖像/文件夾，繪製，使其在這個例子中
