activity页面切换动画

actiyity之间动画切换

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<alpha
android:fromAlpha="0"
android:toAlpha="1"
android:duration="5000"
/>
</set>
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<alpha
android:fromAlpha="1.0"
android:toAlpha="0"
android:duration="5000"
/>
</set>
public void openActivity(View v){
Intent intent = new Intent(this, OtherActivity.class);
startActivity(intent);
this.overridePendingTransition(R.anim.enteralpha, R.anim.outalpha);//实现Activity切换动画效果
}

界面切换，用到了ViewFlipper控件，可以切换图片，触摸切换

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ViewFlipper
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/viewFlipper"
>
<!-- 第一页 -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="第一页"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="打开新Activity"
android:onClick="openActivity"
/>
</LinearLayout>
<!-- 第二页 -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#339900"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="第二页"
/>
</LinearLayout>
</ViewFlipper>
</LinearLayout

实现代码

 @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
in_lefttoright = AnimationUtils.loadAnimation(this, R.anim.enter_lefttoright);
out_lefttoright = AnimationUtils.loadAnimation(this, R.anim.out_lefttoright);

in_righttoleft = AnimationUtils.loadAnimation(this, R.anim.enter_righttoleft);
out_righttoleft = AnimationUtils.loadAnimation(this, R.anim.out_righttoleft);
viewFlipper = (ViewFlipper) this.findViewById(R.id.viewFlipper);
}

@Override
public boolean onTouchEvent(MotionEvent event) {
if(event.getAction()==MotionEvent.ACTION_DOWN){
startX = event.getX();
}else if(event.getAction()==MotionEvent.ACTION_UP){
float endX = event.getX();
if(endX > startX){
viewFlipper.setInAnimation(in_lefttoright);
viewFlipper.setOutAnimation(out_lefttoright);
viewFlipper.showNext();//显示下一页

}else if(endX < startX){
viewFlipper.setInAnimation(in_righttoleft);
viewFlipper.setOutAnimation(out_righttoleft);
viewFlipper.showPrevious();//显示前一页
}
return true;
}
return super.onTouchEvent(event);
}
