我正在尝试将数据存储在ClickableSpan中,就像可以使用setTag()和其他类型的元素来完成数据一样。
我已经在stackoverflow中阅读了以下答案:
SpannableString - setTag
它清楚地说:
-创建自己的ClickableSpan子类,其中包含所需的数据,并将其应用于SpannableString。
-创建ClickableSpan并通过数据成员将单词附加到它时,您将可以在onClick()中访问该数据
但是我有点新手,无法弄清楚如何编写代码。
我正在使用扩展ClickableSpan的类来创建我的可点击范围:
// CLASS BEING IMPORTED
public abstract class TouchableSpan extends ClickableSpan {
// IMPLEMENT SET TAG FUNCTION HERE??
}
// CODE ON ACTIVITY
TouchableSpan touchableSpan = new TouchableSpan() {
@Override
public void onClick(View widget) {
this.setPressed(true);
// GET TAG INFO HERE. BUT HOW?
}
// SET TAG HERE? BUT HOW?
private boolean mIsPressed;
public void setPressed(boolean isSelected) {
mIsPressed = isSelected;
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setColor(Color.BLACK);
ds.bgColor = mIsPressed ? selectedHlColor : 0xffeeeeee;
ds.setUnderlineText(false);
}
}
spannablesstringbuilder.setSpan(touchableSpan, index+2, index2, 0);
评论:我知道我应该在所链接问题的评论部分进行澄清,但我没有足够的声誉。
最佳答案
我认为解决方案是在自定义类中使用自定义函数,这样可能有效
// CLASS BEING IMPORTED
public abstract class TouchableSpan extends ClickableSpan {
// IMPLEMENT SET TAG FUNCTION HERE??
//COMMENT: YES, LIKE THIS: CAN BE ANY FUNCTION U LIKE
private String myCustomVar;
public String getMyVar(){
return this.myCustomVar;
}
public void setMyVar(String myVari){
this.myCustomVar = myVari;
return;
}
}
// CODE ON ACTIVITY
TouchableSpan touchableSpan = new TouchableSpan() {
@Override
public void onClick(View widget) {
this.setPressed(true);
// GET TAG INFO HERE. BUT HOW?
//COMMENT: LIKE THIS:
String extravar = touchableSpan.getMyVar();
Log.d("TEST", extravar);
}
// SET TAG HERE? BUT HOW?
COMMENT: NOT HERE. SEE BELOW
private boolean mIsPressed;
public void setPressed(boolean isSelected) {
mIsPressed = isSelected;
}
@Override
public void updateDrawState(TextPaint ds) {
super.updateDrawState(ds);
ds.setColor(Color.BLACK);
ds.bgColor = mIsPressed ? selectedHlColor : 0xffeeeeee;
ds.setUnderlineText(false);
}
}
//COMMENT: SET YOUR VARIABLE/TAG HERE:
touchableSpan.setMyVar("HOLALA");
spannablesstringbuilder.setSpan(touchableSpan, index+2, index2, 0);
