使用动画的android viewflipper

Question

这是我在动画视图中顺序翻转字符串的编码。

import android.app.Activity; 
import android.os.Bundle; 
import android.view.ViewGroup; 
import android.view.animation.AnimationUtils; 
import android.widget.Button; 
import android.widget.ViewFlipper; 

public class mukesh extends Activity { 
static String[] items={"lorem", "ipsum", "dolor", "sit", "amet", 
"consectetuer", "adipiscing", "elit", 
"morbi", "vel", "ligula", "vitae", 
"arcu", "aliquet", "mollis", "etiam", 
"vel", "erat", "placerat", "ante", 
"porttitor", "sodales", "pellentesque", 
"augue", "purus"}; 
ViewFlipper flipper; 
@Override 
public void onCreate(Bundle icicle) { 
super.onCreate(icicle); 
setContentView(R.layout.main); 
flipper=(ViewFlipper)findViewById(R.id.details); 
flipper.setInAnimation(AnimationUtils.loadAnimation(this, 
R.anim.push_left_in)); 
flipper.setOutAnimation(AnimationUtils.loadAnimation(this, 
R.anim.push_left_out)); 
for (String item : items) { 
Button btn=new Button(this); 
btn.setText(item); 
flipper.addView(btn, 

new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT, 
ViewGroup.LayoutParams.FILL_PARENT)); 
} 
flipper.setFlipInterval(2000); 
flipper.startFlipping(); 
} 
} 

但是“R.anim.push_left_in”这一行显示了error.R.anim无法解析的问题。我们如何解决这个问题

Answer 1

检查您是否在res/anim文件夹中有文件push_left_in.xml。

如果您正在使用Eclipse并且您可以确认您有该文件，请尝试清理项目（Menu/Project/Clean），然后再次尝试构建它。
