ViewFlipper Animation 施用

ViewFlipper Animation 使用

ViewFlipper?

[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"    ><Buttonandroid:id="@+id/previousButton"      android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="Previous"    />    <Buttonandroid: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));

?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;    }
