我希望在加载几秒钟后添加淡入和淡出到启动画面。是否有一个样本用于我的飞溅布局?

这是活动之间缓慢过渡的一个例子。您可以添加自己的动画:
public class OneActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.one);
((Button)findViewById(R.id.next_button)).setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
startActivity(new Intent(OneActivity.this, TwoActivity.class));
overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_left);
}
});
}
}
<强> slide_in_left.xml:强>
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="100%p" android:toXDelta="0%p"
android:duration="@android:integer/config_longAnimTime"/>
<强> slide_out_left.xml:强>
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0" android:toXDelta="-100%p"
android:duration="@android:integer/config_longAnimTime" />
淡入和淡出效果:
<!-- Fade out -->
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0"
android:duration="300" />
<!-- Fade in -->
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="300" />
<!-- Slide in right and slide out right -->
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="-100%p" android:toXDelta="0%p"
android:duration="@android:integer/config_longAnimTime" />
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0" android:toXDelta="100%p"
android:duration="@android:integer/config_longAnimTime" />

是的,您可以向活动,视图等添加动画......
检查帖子 Animation Resources 以获得应用动画的想法。
