我的应用程序有问题:我想在重复动画但未onAnimationRepeat
调用函数(来自AnimationListener
类)时修改 ImageView。
这是重现它的示例:
- 创建一个新项目“test”(Android 2.1,API 7)(我用于
com.test.test
包名) anim
在文件夹内创建一个文件res
夹并fade_in.xml
使用这些行创建
活动代码:
package com.test.test;
import android.app.Activity;
import android.graphics.Color;
import android.graphics.PorterDuff.Mode;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.view.animation.Animation.AnimationListener;
import android.widget.Button;
import android.widget.ImageView;
public class TestActivity extends Activity {
Button button = null;
ImageView image = null;
Animation animation = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button)findViewById(R.id.button1);
image = (ImageView)findViewById(R.id.imageView1);
animation = AnimationUtils.loadAnimation(this, R.anim.fade_in);
animation.setAnimationListener(new AnimationListener() {
int repeatNumber = 0;
@Override
public void onAnimationStart(Animation animation) {Log.i("start", "start");}
@Override
public void onAnimationEnd(Animation animation) {Log.i("end", "end");}
@Override
public void onAnimationRepeat(Animation animation) {
repeatNumber++;
Log.i("repeat", String.valueOf(repeatNumber));
switch(repeatNumber)
{
case 1:image.setColorFilter(Color.RED, Mode.MULTIPLY);break;
case 2:image.setColorFilter(Color.BLUE, Mode.MULTIPLY);break;
case 3:image.setColorFilter(Color.YELLOW, Mode.MULTIPLY);break;
default:break;
}
}
});
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {image.startAnimation(animation);}
});
}
}
和布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" />
</LinearLayout>
ImageView
颜色没有变化……你能帮帮我吗?
