## android5.0之animated-selector ##

### 先看效果图： ###

![这里写图片描述][20160619142901337]

### 在res/drawable/目录下创建一个animator\_selector.xml文件 ###

<?xml version="1.0" encoding="utf-8"?>
    <animated-selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:id="@+id/state_on" android:drawable="@drawable/btn_check_0" android:state_checked="false" />
    
        <item android:id="@+id/state_off" android:state_checked="true" android:drawable="@drawable/btn_check_15" />
    
        <transition android:fromId="@id/state_on" android:toId="@id/state_off">
            <animation-list>
                <item android:drawable="@drawable/btn_check_0" android:duration="30" />
                <item android:drawable="@drawable/btn_check_1" android:duration="30" />
                <item android:drawable="@drawable/btn_check_2" android:duration="30" />
                <item android:drawable="@drawable/btn_check_3" android:duration="30" />
                <item android:drawable="@drawable/btn_check_4" android:duration="30" />
                <item android:drawable="@drawable/btn_check_5" android:duration="30" />
                <item android:drawable="@drawable/btn_check_6" android:duration="30" />
                <item android:drawable="@drawable/btn_check_7" android:duration="30" />
                <item android:drawable="@drawable/btn_check_8" android:duration="30" />
                <item android:drawable="@drawable/btn_check_9" android:duration="30" />
                <item android:drawable="@drawable/btn_check_10" android:duration="30" />
                <item android:drawable="@drawable/btn_check_11" android:duration="30" />
                <item android:drawable="@drawable/btn_check_12" android:duration="30" />
                <item android:drawable="@drawable/btn_check_13" android:duration="30" />
                <item android:drawable="@drawable/btn_check_14" android:duration="30" />
                <item android:drawable="@drawable/btn_check_15" android:duration="30" />
            </animation-list>
        </transition>
    </animated-selector>

*有点类似帧动画*

### 给对应的控件设置，如下： ###

### 代码中： ###

public class MainActivity extends AppCompatActivity { 
    
    
        private ImageView iv;
        private static final int[] STATE_CHECKED = new int[]{android.R.attr.state_checked};
        private static final int[] STATE_UNCHECKED = new int[]{};
        private boolean flag;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            iv = (ImageView) findViewById(R.id.check);
    
            iv.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (flag) {
                        iv.setImageState(STATE_UNCHECKED, true);
                        flag = false;
                    } else {
                        iv.setImageState(STATE_CHECKED, true);
                        flag = true;
                    }
                }
            });
    
        }
    }
