Android 现有ImageView上的AnimationDrawable将不会设置动画
我有以下代码,用于在应用另一个动画后将动画添加到ImageView 动画从未开始。以下是相关代码:Android 现有ImageView上的AnimationDrawable将不会设置动画,android,android-layout,animationdrawable,Android,Android Layout,Animationdrawable,我有以下代码,用于在应用另一个动画后将动画添加到ImageView 动画从未开始。以下是相关代码: // I'm Using Jake Wharton's ButterKnife,a view "injection" library. @InjectView(R.id.record_button) public ImageView recordButtonView; protected void onCreate(Bundle savedInstance) { ... But
// I'm Using Jake Wharton's ButterKnife,a view "injection" library.
@InjectView(R.id.record_button)
public ImageView recordButtonView;
protected void onCreate(Bundle savedInstance) {
...
ButterKnife.inject(this);
pulsate = AnimationUtils.loadAnimation(this.parent, R.anim.pulsate);
recordButtonView.startAnimation(pulsate)
...
}
@OnClick(R.id.record_button)
protected void onButtonClick( ) {
...
// Clear the old animation
recordButtonView.clearAnimation();
// Start the new animation
recordButtonView.setBackgroundResource(R.drawable.record_button_animation);
AnimationDrawable recordButtonAnimation = (AnimationDrawable) recordButtonView.getBackground();
recordButtonAnimation.setCallback(recordButtonView);
recordButtonAnimation.setVisible(true, true);
recordButtonAnimation.start();
// At this point the animation should be looping. Nothing happens
...
}
这是record_button_animation.xml(保存在res/drawable上)
下面是相应的布局文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- all sibling elements are removed for clarity -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/stem">
<!-- all sibling elements are removed for clarity -->
<ImageView
android:id="@+id/record_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/sing_btn_record"
android:scaleType="center"
android:layout_centerInParent="true"/>
</RelativeLayout>
</RelativeLayout>
希望这有助于:
@OnClick(R.id.record_button)
protected void onButtonClick( ) {
...
// Clear the old animation
recordButtonView.clearAnimation();
// Start the new animation
recordButtonView.setBackgroundResource(R.drawable.record_button_animation);
// Following line worked for me
recordButtonView.setAnimation(pulsate);
// At this point the animation should be looping. Nothing happens
...
}
试试这个
ImageView recordButton = (ImageView) findViewById(R.id.imageViewPulse);
recordButton.setImageBitmap(null);
recordButton.setBackgroundResource( R.anim.pulse );
final AnimationDrawable mailAnimation = (AnimationDrawable) recordButton.getBackground();
recordButton.post(new Runnable() {
public void run() {
if ( mailAnimation != null ) mailAnimation.start();
}
});
不幸的是,这没有帮助。初始动画(脉动)只是再次开始,但不是R.drawable.record_按钮_动画中定义的动画)
ImageView recordButton = (ImageView) findViewById(R.id.imageViewPulse);
recordButton.setImageBitmap(null);
recordButton.setBackgroundResource( R.anim.pulse );
final AnimationDrawable mailAnimation = (AnimationDrawable) recordButton.getBackground();
recordButton.post(new Runnable() {
public void run() {
if ( mailAnimation != null ) mailAnimation.start();
}
});
