Android淘宝好评星级进度条RatingBar原来可以这么玩

系统自带的比较老土

布局文件：activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <RatingBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/rb_normal"
        android:layout_gravity="center_horizontal" />
LinearLayout>

展示视图控制文件：MainActivity

package com.example.lenovo.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.widget.RatingBar;
import android.widget.Toast;

public class MainActivity extends Activity{

    private RatingBar rb_normal;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rb_normal = (RatingBar) findViewById(R.id.rb_normal);
        rb_normal.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                Toast.makeText(MainActivity.this, "rating:" + String.valueOf(rating),
                        Toast.LENGTH_LONG).show();
            }
        });
    }
}

我们来定制一下吧，不要星星要笑脸

哈哈效果不太好，借的图，怎么调试那一半笑脸也对不上，有兴趣的可以试试

布局文件：activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <RatingBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="@style/roomRatingBar"
        android:id="@+id/rb_normal"
        android:layout_gravity="center_horizontal"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />
RelativeLayout>

展示视图控制文件：MainActivity

package com.example.lenovo.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.widget.RatingBar;
import android.widget.Toast;

public class MainActivity extends Activity{

    private RatingBar rb_normal;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        rb_normal = (RatingBar) findViewById(R.id.rb_normal);
        rb_normal.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                Toast.makeText(MainActivity.this, "rating:" + String.valueOf(rating),
                        Toast.LENGTH_LONG).show();
            }
        });
    }
}

注意笑脸怎么来的呢

rating_off.png

rating_on.png

笑脸设置文件ratingbar_full.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background"
        android:drawable="@drawable/rating_off" />
    <item android:id="@android:id/secondaryProgress"
        android:drawable="@drawable/rating_off" />
    <item android:id="@android:id/progress"
        android:drawable="@drawable/rating_on" />
layer-list>

风格文件style.xml

注意其他都是系统自带的，只有roomRatingBar有用
