android image加载中等待动画

在布局中添加一个ImageViw和一个EditText。

  <ImageView
        android:id="@+id/loading_imageView_info"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="@anim/loading" />

    <EditText
        android:id="@+id/loading_editText_info"
        android:layout_width="0dp"
        android:layout_height="0dp" />

 

 

	private ImageView loadingImageView ;
	private EditText loadingEditText;
	private AnimationDrawable anim;
 

 loadingImageView =(ImageView)findViewById(R.id.loading_imageView_info);
		loadingEditText =(EditText)findViewById(R.id.loading_editText_info);
		loadingEditText.setInputType(InputType.TYPE_NULL);//屏蔽软键盘
		
		anim = (AnimationDrawable) loadingImageView.getBackground();
		loadingEditText.setOnFocusChangeListener(editSetOnFocus);

 

/**
		 * 当输入框获取焦点，则运行动画
		 */
		private  OnFocusChangeListener editSetOnFocus = new OnFocusChangeListener() {
			
			@Override
			public void onFocusChange(View v, boolean hasFocus) {
				// TODO Auto-generated method stub
				anim.start();
				Log.i("text", "执行等待动画。。。。。。。。");
			}
		}; 

 

 

    当程序获取到数据一般情况是在hanlder中发送消息通知动画停止，并隐藏当前的控件

  

     anim.stop();
     loadingImageView.setVisibility(View.GONE);

 

anim动画在XML中定义，代码如下：

 

<?xml version="1.0" encoding="UTF-8"?>  
<animation-list android:oneshot="false" xmlns:android="http://schemas.android.com/apk/res/android">  

	<item android:duration="150" android:drawable="@drawable/load1" /> 
	<item android:duration="150" android:drawable="@drawable/load2" /> 
	<item android:duration="150" android:drawable="@drawable/load3" /> 
	<item android:duration="150" android:drawable="@drawable/load4" /> 
	<item android:duration="150" android:drawable="@drawable/load5" /> 
	<item android:duration="150" android:drawable="@drawable/load6" /> 
	
</animation-list>
