android image加载中等待动画

Xml代码


在布局中添加一个ImageViw和一个EditText。

Xml代码


<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" />

Java代码


<pre class="java" name="code"> private ImageView loadingImageView ;

private EditText loadingEditText;

private AnimationDrawable anim;</pre>

Java代码


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);

Java代码


/**

* 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

Java代码


anim.stop();

loadingImageView.setVisibility(View.GONE);

anim动画在XML中定义，代码如下：

Java代码


<?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>
