我正在做一个Android应用程序,它具有图像缩放动画控制,带有start&停止按钮。(即)我有两个带图像的按钮。当我点击开始时,图像应该做缩放动画。当我点击停止时,它应该停止动画。再次,如果我点击开始,它应该恢复从停止的位置。我怎么能这样做? 以下是我的工作示例代码:
ImageView imageView; ScaleAnimation缩放; 动画动画; float gg;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
zoom = new ScaleAnimation(0, 1, 0, 1);
zoom.setDuration(3000);
imageView = (ImageView) findViewById(R.id.imageView1);
imageView.startAnimation(zoom);
((Button) findViewById(R.id.start)).setOnClickListener(this);
((Button) findViewById(R.id.stop)).setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.start:
zoom.setDuration((long) gg);
zoom.start();
break;
case R.id.stop:
gg = zoom.getDuration();
break;
}
}
} 感谢。

试试这个
活动中的ZOOM
public class ZoomInActivity extends Activity implements AnimationListener {
ImageView imgPoster;
Button btnStart;
// Animation
Animation animZoomIn;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_zoom_in);
imgPoster = (ImageView) findViewById(R.id.imgLogo);
btnStart = (Button) findViewById(R.id.btnStart);
// load the animation
animZoomIn = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.zoom_in);
// set animation listener
animZoomIn.setAnimationListener(this);
// button click event
btnStart.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// start the animation
imgPoster.startAnimation(animZoomIn);
}
});
}
@Override
public void onAnimationEnd(Animation animation) {
// Take any action after completing the animation
// check for zoom in animation
if (animation == animZoomIn) {
}
}
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
}
activity_zoom_in_XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:gravity="center">
<ImageView android:id="@+id/imgLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/man_of_steel"
android:layout_centerInParent="true"/>
<Button android:id="@+id/btnStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start Animation"
android:layout_marginTop="30dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="20dp"/>
</RelativeLayout>
在res中创建anim文件夹并创建zoom_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true" >
<scale
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromXScale="1"
android:fromYScale="1"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="3"
android:toYScale="3" >
</scale>
</set>

简单易用
使用以下代码
将动画设置为图像ImageView image=(ImageView)findViewById(R.id.imageId);
image.setAnimation(AnimationUtils.loadAnimation(this,R.anim.zoom_in_anim));
