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

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