Android ViewFlipper 用例

[功能]
1. ViewFlipper 可以包含多个View 且View之间的切换有Animation  比如：渐变效果


[代码]
1. 创建包含ViewFlipper 的main.xml 还包含2个Button 用于各个View切换

<?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"
    >
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
    <Button
    android:id="@+id/previousButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Previous"
    />
    <Button
    android:id="@+id/nextButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Next"
    />
    </LinearLayout>
<ViewFlipper
    android:id="@+id/flipper"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    >
</ViewFlipper>
</LinearLayout>

<?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"
    >
	<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
	<Button
	android:id="@+id/previousButton"  
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Previous"
    />
    <Button
	android:id="@+id/nextButton"  
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Next"
    />
    </LinearLayout>
<ViewFlipper  
	android:id="@+id/flipper"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:gravity="center"
    >
</ViewFlipper>
</LinearLayout>

2. 设定 Animation 效果

flipper = (ViewFlipper) findViewById(R.id.flipper);
flipper.setInAnimation(AnimationUtils.loadAnimation(this,
                android.R.anim.fade_in));
flipper.setOutAnimation(AnimationUtils.loadAnimation(this,
                android.R.anim.fade_out));

flipper = (ViewFlipper) findViewById(R.id.flipper);
flipper.setInAnimation(AnimationUtils.loadAnimation(this,
                android.R.anim.fade_in));
flipper.setOutAnimation(AnimationUtils.loadAnimation(this,
                android.R.anim.fade_out));

3. 在 ViewFlipper  里面增加各种View

flipper.addView(addTextByText("HelloAndroid"));
        flipper.addView(addImageById(R.drawable.beijing_003_mb5ucom));
        flipper.addView(addTextByText("eoe.Android"));
        flipper.addView(addImageById(R.drawable.beijing_004_mb5ucom));
        flipper.addView(addTextByText("Gryphone"));

ublic View addTextByText(String text){
            TextView tv = new TextView(this);
            tv.setText(text);
            tv.setGravity(1);
            return tv;
    }

    public View addImageById(int id){
        ImageView iv = new ImageView(this);
        iv.setImageResource(id);

        return iv;
    }

flipper.addView(addTextByText("HelloAndroid"));
        flipper.addView(addImageById(R.drawable.beijing_003_mb5ucom));
        flipper.addView(addTextByText("eoe.Android"));
        flipper.addView(addImageById(R.drawable.beijing_004_mb5ucom));
        flipper.addView(addTextByText("Gryphone"));

ublic View addTextByText(String text){
    		TextView tv = new TextView(this);
    		tv.setText(text);
    		tv.setGravity(1);
    		return tv;
    }
    
    public View addImageById(int id){
		ImageView iv = new ImageView(this);
		iv.setImageResource(id);
		
		return iv;
    }

4. View 切换
* 下一个View

flipper.showNext();

flipper.showNext();

* 上一个View

flipper.showPrevious();

flipper.showPrevious();

现释出所有代码!
