SlidingDrawer是自SDK 1.5才新加入的,實現Launcher的抽屜效果。SlidingDrawer配置上採用了水平展開或垂直展開兩種(android:orientation)方式,在XML裏必須指定其使用的android:handle與android:content,前者委託要展開的圖片(Layout配置),後者則是要展開的Layout Content。android
- <?xml version="1.0" encoding="utf-8"?>
-
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
-
- android:orientation="vertical"
-
- android:layout_width="fill_parent"
-
- android:layout_height="fill_parent"
-
- android:background="@drawable/i1"
-

-
- <SlidingDrawer
-

1、簡介 SlidingDrawer隱藏屏外的內容,並容許用戶經過handle以顯示隱藏內容。它能夠垂直或水平滑動,它有倆個View組成,其一是能夠拖動的handle,其二是隱藏內容的View.它裏面的控件必須設置佈局,在佈局文件中必須指定handle和content. 例以下面 <SlidingDrawer android:layout_width="fill_parent" android:layout_height="fill_parent" android:handle="@+id/handle" android:content="@+id/content" android:orientation="vertical" android:id="@+id/slidingdrawer"> <ImageButton android:id="@id/handle" android:layout_width="50dip" android:layout_height="44dip" android:src="@drawable/up" /> <LinearLayout android:id="@id/content" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff"> <TextView android:text="這是一個滑動式抽屜的示例" android:id="@+id/tv" android:textSize="18px" android:textColor="#000000" android:gravity="center_vertical|center_horizontal" android:layout_width="match_parent" android:textStyle="bold" android:layout_height="match_parent"></TextView> </LinearLayout> </SlidingDrawer> 2、重要屬性 android:allowSingleTap:指示是否能夠經過handle打開或關閉 android:animateOnClick:指示是否當使用者按下手柄打開/關閉時是否該有一個動畫。 android:content:隱藏的內容 android:handle:handle(手柄) 3、重要方法 animateClose():關閉時實現動畫。 close():即時關閉 getContent():獲取內容 isMoving():指示SlidingDrawer是否在移動。 isOpened():指示SlidingDrawer是否已所有打開 lock():屏蔽觸摸事件。 setOnDrawerCloseListener(SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener):SlidingDrawer關閉時調用 unlock():解除屏蔽觸摸事件。 toggle():切換打開和關閉的抽屜SlidingDrawer。 4、完整實例 1.佈局文件slidingdrawer.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="@drawable/default_bg"> <SlidingDrawer android:layout_width="fill_parent" android:layout_height="fill_parent" android:handle="@+id/handle" android:content="@+id/content" android:orientation="vertical" android:id="@+id/slidingdrawer"> <ImageButton android:id="@id/handle" android:layout_width="50dip" android:layout_height="44dip" android:src="@drawable/up" /> <LinearLayout android:id="@id/content" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff"> <TextView android:text="這是一個滑動式抽屜的示例" android:id="@+id/tv" android:textSize="18px" android:textColor="#000000" android:gravity="center_vertical|center_horizontal" android:layout_width="match_parent" android:textStyle="bold" android:layout_height="match_parent"></TextView> </LinearLayout> </SlidingDrawer> </LinearLayout> 2.Java代碼 package com.wjq; import android.app.Activity; import android.os.Bundle; import android.widget.ImageButton; import android.widget.SlidingDrawer; import android.widget.TextView; public class SlidingDrawerDemo extends Activity { private SlidingDrawer mDrawer; private ImageButton imbg; private Boolean flag=false; private TextView tv; /* (non-Javadoc) * @see android.app.Activity#onCreate(android.os.Bundle) */ @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.sildingdrawer); imbg=(ImageButton)findViewById(R.id.handle); mDrawer=(SlidingDrawer)findViewById(R.id.slidingdrawer); tv=(TextView)findViewById(R.id.tv); mDrawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() { @Override public void onDrawerOpened() { flag=true; imbg.setImageResource(R.drawable.down); } }); mDrawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener(){ @Override public void onDrawerClosed() { flag=false; imbg.setImageResource(R.drawable.up); } }); mDrawer.setOnDrawerScrollListener(new SlidingDrawer.OnDrawerScrollListener(){ @Override public void onScrollEnded() { tv.setText("結束拖動"); } @Override public void onScrollStarted() { tv.setText("開始拖動"); } }); } } |
