近来公司有个新功能就是投票功能，在网上找了一圈，没看到怎么完全适合的，自己和童鞋搞了个，在此记录下。

UI是这样的；

一开始打算用ProgressBar实现，做出来的效果不是完全符合需求有点小Bug，然后自定义了一个。

首先是drawable样式left_blue_radius_shape.xml：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#2AA7FF" />
    <corners
        android:bottomLeftRadius="60dp"
        android:bottomRightRadius="0dp"
        android:topLeftRadius="60dp"
        android:topRightRadius="0dp" />
</shape>

left_radius_shape.xml 

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FF9393" />
    <corners
        android:bottomLeftRadius="60dp"
        android:bottomRightRadius="0dp"
        android:topLeftRadius="60dp"
        android:topRightRadius="0dp" />
</shape>

left_rectangle_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FF9393" />
</shape>

radius_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/white" />
    <corners
        android:bottomLeftRadius="60dp"
        android:bottomRightRadius="60dp"
        android:topLeftRadius="60dp"
        android:topRightRadius="60dp" />
</shape>

right_radius_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#2AA7FF" />
    <corners
        android:bottomLeftRadius="0dp"
        android:bottomRightRadius="60dp"
        android:topLeftRadius="0dp"
        android:topRightRadius="60dp" />
</shape>

right_rectangle_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#2AA7FF" />
</shape>

right_red_radius_shape.xml 

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FF9393" />
    <corners
        android:bottomLeftRadius="0dp"
        android:bottomRightRadius="60dp"
        android:topLeftRadius="0dp"
        android:topRightRadius="60dp" />
</shape>

 控件item，layout_vote_item.xml

<?xml version="1.0" encoding="utf-8"?>

自定义控件代码 VoteView.java；

public class VoteView extends LinearLayout {
    private Context context;
    private LinearLayout llContent;
    private TextView tvApproveOfTv, tvApproveOf, tvOppose, tvOpposeTv;

    public VoteView(Context context) {
        super(context);
    }

    public VoteView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
        initView();
    }

    public VoteView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {

        if (scaleApproveOf == 1) {

    }

    public void setApproveOf(String approveOfText) {
        if (TextUtils.isEmpty(approveOfText)) return;
        tvApproveOfTv.setText(approveOfText);
    }

    public void setOppose(String opposeText) {
        if (TextUtils.isEmpty(opposeText)) return;
        tvOpposeTv.setText(opposeText);
    }
}

使用方法：

 在布局文件中使用
  

   
   <com.gx.widgetlibrary.VoteView
        android:id="@+id/vv_1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

代码中设置比例：

vv_1.setApproveOf(30 + "");
	vv_1.setOppose(70 + "");
	vv_1.setWeightForView(0.3F);
