1. 透明动画 按钮透明
① 用代码控制
创建一个按钮
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/btnClickMe" />
</LinearLayout>
public class MainActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.findViewById(R.id.btnClickMe).setOnClickListener(new View.OnClickListener() { //按钮点击监听
@Override
public void onClick(View v) {
// 透明动画 透明效果从 0->1
AlphaAnimation aa = new AlphaAnimation(0, 1);
aa.setDuration(1000); // 时间设置 1s
v.startAnimation(aa); // 把按钮设置改动画
}
});
System.out.println("onCreate");
}
}
② 用 anim目录下面的xml配置文件来实现
在 res/anim/aa.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- fromAlpha从0 toAlpha到1 duration时间1s-->
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="0"
android:toAlpha="1"
android:duration="1000"
/>
public class MainActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.findViewById(R.id.btnClickMe).setOnClickListener(new View.OnClickListener() { //按钮点击监听
@Override
public void onClick(View v) {
/*// 透明动画 透明效果从 0->1
AlphaAnimation aa = new AlphaAnimation(0, 1);
aa.setDuration(1000); // 时间设置 1s
v.startAnimation(aa); // 把按钮设置改动画*/
// 用配置文件来实现
v.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.aa));
}
});
System.out.println("onCreate");
}
}
2. 旋转动画
视图界面 -- 一个按钮
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/btnClickMe"
android:layout_centerVertical="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
①直接使用java代码
public class MainActivity extends Activity{
private RotateAnimation ra = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//ra = new RotateAnimation(0, 360); // 默认从0,0 旋转360度
//ra = new RotateAnimation(0, 360 ,10, 10); // 从 10,10 旋转360度
ra = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
ra.setDuration(1000); //时间 1s
this.findViewById(R.id.btnClickMe).setOnClickListener(new View.OnClickListener() { //按钮点击监听
@Override
public void onClick(View v) {
v.startAnimation(ra); //用代码
}
});
System.out.println("onCreate");
}
}
② 用配置文件 xml /res/anim/rotate.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:duration="1000"
android:pivotX="50%"
android:pivotY="50%"
/>
java代码
public class MainActivity extends Activity{
private RotateAnimation ra = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.findViewById(R.id.btnClickMe).setOnClickListener(new View.OnClickListener() { //按钮点击监听
@Override
public void onClick(View v) {
//用xml文件
v.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.rotate));
}
});
System.out.println("onCreate");
}
}
3. 移动动画
视图----- 一个按钮
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="@+id/btnClickMe"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
① 直接用java
public class MainActivity extends Activity{
private TranslateAnimation ta = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ta = new TranslateAnimation(0, 200, 0, 200); // x + 200 y+200
ta.setDuration(1000);// 1s 时间
this.findViewById(R.id.btnClickMe).setOnClickListener(new View.OnClickListener() { //按钮点击监听
@Override
public void onClick(View v) {
v.startAnimation(ta);
}
});
System.out.println("onCreate");
}
}
② anim/translate.xml 文件
<?xml version="1.0" encoding="utf-8"?>
<translate android:fromXDelta="0" android:fromYDelta="0" android:toXDelta="200"
android:toYDelta="200"
android:duration="1000"
xmlns:android="http://schemas.android.com/apk/res/android" />
public class MainActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.findViewById(R.id.btnClickMe).setOnClickListener(new View.OnClickListener() { //按钮点击监听
@Override
public void onClick(View v) {
// 调用配置文件 执行
v.startAnimation(AnimationUtils.loadAnimation(v.getContext(), R.anim.translate));
}
});
System.out.println("onCreate");
}
}
