由于项目需要一个评分控件,搜了一下网上的。代码太多。功能太强大,使用太麻烦,索性就自己写了一个。
也由于实在是懒,所以,就不自定义属性了。先能用就行。等哪天心情好了再把它优化好吧。
public class RatingStart extends LinearLayout {
private int startIconResId;
private int padding = 20;
private int numStars = 5;
private ImageView[] imageViews;
private int currentSelectedIndex = -1;
public RatingStart(Context context) {
super(context);
init();
}
public RatingStart(Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
init();
}
private void init() {
this.setOrientation(LinearLayout.HORIZONTAL);
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
}
public void build() {
this.removeAllViews();
imageViews = new ImageView[numStars];
for (int i = 0; i < numStars; i++) {
ImageView imageView = new ImageView(this.getContext());
imageView.setImageResource(startIconResId);
imageView.setPadding(padding , 0, padding , 0);
addView(imageView);
imageViews[i] = imageView;
imageView.setOnClickListener(new ImageClickListener(i));
}
}
private class ImageClickListener implements View.OnClickListener {
private int index;
public ImageClickListener(int index) {
this.index = index;
}
@Override
public void onClick(View v) {
currentSelectedIndex = index;
for (int i = 0; i < imageViews.length; i++) {
imageViews[i].setSelected(i <= index);
}
}
}
public void setStartIconResId(int startIconResId) {
this.startIconResId = startIconResId;
}
public void setPadding(int padding) {
this.padding = padding;
}
public void setNumStars(int numStars) {
this.numStars = numStars;
}
public int getCurrentSelectedIndex() {
return currentSelectedIndex;
}
}
然后在需要的XML 里面
<com.ls.testsdk.widget.RatingStart
android:id="@+id/radtingStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
最后在activity
radtingStart.setPadding(20);
radtingStart.setNumStars(5);
radtingStart.setStartIconResId(R.drawable.service_evaluating_start_bg);
radtingStart.build();
