如何获得的RatingBar值 [英] how to get RatingBar value

问题描述

如何阅读和显示等级栏值

  I [0] //应选择值

私人OnClickListener onclickbutton1 =新OnClickListener（）{
    公共无效的onClick（视图v）{
        INT [1 =新的INT [] {R.id.mRatingBar};

        statusMessage.setText（值是+ I [0]）;
    }
};
 

//这个作品

 私人OnClickListener onclickbutton1 =新OnClickListener（）{
    公共无效的onClick（视图v）{
        的RatingBar毫巴=（的RatingBar）findViewById（R.id.mRatingBar）;

        浮[1 =新的浮动[] {m​​Bar.getRating（）};

        statusMessage.setText（值。+ I [0]）;
    }
};
 

解决方案

什么你在这里做是不对的。你输出的评级杆的资源ID，而不是它的价值

让我假设你已经做得比较早是这样的：

 的RatingBar毫巴=（的RatingBar）findViewById（R.id.mRatingBar）;
mBar.setOnClickListener（onclickbutton1）;
 

例如，在活动的的onCreate（）。然后在点击侦听器内提供，你可以得到的评级如下：

 公共无效的onClick（视图v）{
    的RatingBar栏=（的RatingBar）V;
    statusMessage.setText（值是+ bar.getRating（））;
}
 

how to read and display rating bar value

i[0] // should be selected value

private OnClickListener onclickbutton1 = new OnClickListener() {
    public void onClick(View v) {
        int[] i = new int[]{ R.id.mRatingBar};

        statusMessage.setText("value is " + i[0]);
    }
};

// this works

private OnClickListener onclickbutton1 = new OnClickListener() {
    public void onClick(View v) {
        RatingBar mBar = (RatingBar) findViewById(R.id.mRatingBar);

        float[] i = new float[]{ mBar.getRating() };

        statusMessage.setText("value is.. " + i[0]);
    }
};

解决方案

What you do here is not right: you output the resource id of the rating bar, not its value.

Let me assume that you have earlier done something like:

RatingBar mBar = (RatingBar) findViewById(R.id.mRatingBar);
mBar.setOnClickListener(onclickbutton1);

for example in the activity's onCreate(). Then within the on click listener you provide, you can get the rating as follows:

public void onClick(View v) {
    RatingBar bar = (RatingBar) v;
    statusMessage.setText("value is " + bar.getRating());
}
