[android] Android에서 사용자 지정 등급 표시 줄을 만드는 방법
안녕하세요, 내 응용 프로그램에서 등급을 수행하는 데 필요한 모든 것입니다 … 그래서 사용자 지정 등급 표시 줄을 만들어야합니다 … 누구든지이 작업을 도와 줄 수 있나요?

<item name="android:minHeight">23dip</item>

</style>
</resources>
food_rating_bar_full.xml
이 파일은 Drawable 폴더에 있어야합니다.
<?xml version="1.0" encoding="utf-8"?>

<item android:id="@+id/progress"
android:drawable="@drawable/food_ratingbar_full_filled" />
</layer-list>
food_ratingbar_full_empty.xml
이 파일은 Drawable 폴더 안에 있어야합니다.
<?xml version="1.0" encoding="utf-8"?>
<!-- This is the rating bar drawable that is used to
show a filled cookie. -->
<selector

food_ratingbar_full_filled.xml
이 파일은 Drawable 폴더에 있어야합니다.

<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="@drawable/cookie" />
<item android:drawable="@drawable/cookie" />
</selector>
main.xml 파일은 다음과 같아야합니다.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RatingBar android:id="@+id/ratingBar1"
style="@style/foodRatingBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RatingBar>
</LinearLayout>
MainActivity.class는 다음과 같아야합니다.
import android.app.Activity;
import android.os.Bundle;
import android.widget.RatingBar;
import android.widget.RatingBar.OnRatingBarChangeListener;
import android.widget.Toast;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
RatingBar rb;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
rb=(RatingBar)findViewById(R.id.ratingBar1);
rb.setOnRatingBarChangeListener(new OnRatingBarChangeListener(){
@Override
public void onRatingChanged(RatingBar ratingBar, float rating,
boolean fromUser) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),Float.toString(rating),Toast.LENGTH_LONG).show();
}
});
}
}
두 개의 이미지를 사용했습니다.
cookie.jpg
cookiee.jpg
이 두 이미지는 동일한 크기입니다. 하나는 선택한 Rating Bar를 식별하는 데 사용되고 다른 하나는 선택되지 않은 RatingBar를 식별하는 데 사용됩니다.
답변
위의 것보다 더 쉬운 내 솔루션을 추가해야합니다. 스타일을 사용할 필요조차 없습니다.
드로어 블 폴더에 선택기 파일을 만듭니다.
custom_ratingbar_selector.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/star_off" />
<item android:id="@android:id/secondaryProgress"
android:drawable="@drawable/star_off" />
<item android:id="@android:id/progress"
android:drawable="@drawable/star_on" />
</layer-list>
레이아웃에서 선택기 파일을 progressDrawable로 설정합니다.
<RatingBar
android:id="@+id/ratingBar2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:progressDrawable="@drawable/custom_ratingbar_selector"
android:numStars="8"
android:stepSize="0.2"
android:rating="3.0" />
그게 우리에게 필요한 전부입니다.
답변
먼저 드로어 블에 이미지를 추가합니다.
첫 번째 사진은 “ratingbar_staroff.png”이고 두 번째 사진은 “ratingbar_staron.png”입니다.
그 후 res / drawable에 “ratingbar.xml”을 생성하십시오.
<?xml version="1.0" encoding="utf-8"?>
<!--suppress AndroidDomInspection -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+android:id/background"
android:drawable="@drawable/ratingbar_empty" />
<item android:id="@+android:id/secondaryProgress"
android:drawable="@drawable/ratingbar_empty" />
<item android:id="@+android:id/progress"
android:drawable="@drawable/ratingbar_filled" />
</layer-list>
res / drawable에서 동일한 다음 XML
“ratingbar_empty.xml”
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_window_focused="true"
android:drawable="@drawable/ratingbar_staroff" />
<item android:state_focused="true"
android:state_window_focused="true"
android:drawable="@drawable/ratingbar_staroff" />
<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="@drawable/ratingbar_staroff" />
<item android:drawable="@drawable/ratingbar_staroff" />
</selector>
“ratingbar_filled”
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:state_window_focused="true"
android:drawable="@drawable/ratingbar_staron" />
<item android:state_focused="true"
android:state_window_focused="true"
android:drawable="@drawable/ratingbar_staron" />
<item android:state_selected="true"
android:state_window_focused="true"
android:drawable="@drawable/ratingbar_staron" />
<item android:drawable="@drawable/ratingbar_staron" />
</selector>
다음으로 res / values / styles에 다음 코드 줄을 추가하십시오.
<style name="CustomRatingBar" parent="@android:style/Widget.RatingBar">
<item name="android:progressDrawable">@drawable/ratingbar</item>
<item name="android:minHeight">18dp</item>
<item name="android:maxHeight">18dp</item>
</style>
이제 이미 ratingbar 리소스에 스타일을 추가 할 수 있습니다.
<RatingBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style= "@style/CustomRatingBar"
android:id="@+id/ratingBar"
android:numStars="5"
android:stepSize="0.01"
android:isIndicator="true"/>
마지막으로 귀하의 활동에만 선언됩니다.
RatingBar ratingbar = (RatingBar) findViewById(R.id.ratingbar);
ratingbar.setRating(3.67f);
답변
레이어 목록 및 선택기로 사용자 지정 등급 표시 줄을 만드는 것은 복잡하므로 RatingBar 클래스를 재정의하고 사용자 지정 RatingBar를 만드는 것이 좋습니다. createBackgroundDrawableShape ()는 빈 상태 png를 넣어야하는 함수이고 createProgressDrawableShape ()는 채워진 상태 png를 넣어야하는 함수입니다.
참고 :이 코드는 현재 svg에서 작동하지 않습니다.

또한 두 개의 SVG 드로어 블을 사용하여 rating_bar.xml을 만들어야합니다.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

디자인 / 분할보기에 별 하나만 표시되는 경우 레이아웃을 새로 고칩니다.

이것이 결과입니다.
- 등급 표시 줄의 실제 높이 (13.4dp)를
layout_height
속성에 추가했습니다. 그럴 경우wrap_content
별 아래에 선이 그려 지기 때문 입니다. (제 경우에는 Android Studio 미리보기에서만)
