Android RatingBar显示超过5星

Question

我想在我的Android应用程序中通过警告对话框显示评级栏.我面临的问题是,根据屏幕的宽度,评级栏在横向模式下显示超过5星(最多10个),而函数setNumStars()无效.有些帖子已经处理过这个问题,但它们处理的是一个评级栏,其中laout是静态定义的,而我是动态创建它的.如何解决这个问题呢？

public class MainActivity extends Activity {
private Button launchButton;
//Rating dialog
 private AlertDialog.Builder rater;
 private RatingBar ratingBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    launchButton =(Button)findViewById(R.id.ratingButton);
    launchButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            //Here the alert dialog will be launched
            showRatingDialog();
        }
    });

      //Setting up rating dialog
        rater = new AlertDialog.Builder(this);

        rater.setTitle("This is the rating dialog");


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
public void showRatingDialog()
{
  ratingBar = (RatingBar)findViewById(R.id.ratingStars);
      rater.setNegativeButton("Abbrechen", null);
      rater.setView(ratingBar);
      rater.show();

}
}

我已尝试使用静态布局进行评级栏,但是当我这样做并尝试通过警告对话框显示评级栏时,不会显示任何星标.这是评级栏的布局文件:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RatingBar
        android:id="@+id/ratingStars"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:numStars="5"
        android:stepSize="1"
        />

</LinearLayout>

Answer 1

将RatingBar的宽度设置为"换行内容"可以解决整个问题.根据文件:

设置要显示的星数.为了正确显示这些内容,建议此窗口小部件的布局宽度为换行内容.

Answer 2

设置android:numStars="5"和android:layout_width="wrap_content"

Answer 3

尝试为您的RatingBarLike Below 设置最大值

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/active_bg" >

    <RatingBar
            android:id="@+id/rating"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            style="?android:attr/ratingBarStyleSmall"
            android:numStars="5"
            android:stepSize="0.1"
            android:isIndicator="true" />

</RelativeLayout>

在布局文件中创建一个xml文件,并将其设置为内容

showDialog像这样改变你的功能

LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.***your_xml_name***));
editor.setView(layout);
editor.show();
