对于(int i=0;i
我希望能够获取刚刚单击的此LinearLayout的子项TextView的值,我如何才能做到这一点?尝试以下方法:
TextView tv = textWrapper.findViewById(//TextView Id);
tv.getText().toString();
试试这个:
TextView tv = textWrapper.findViewById(//TextView Id);
tv.getText().toString();
您可以尝试这样的方法,在onClick()中调用它
for(inti=0;i您可以尝试这样的方法,在onClick()中调用它
for(int i=0;i如果您只有一个孩子,则得到如下结果:
TextView tv = (TextView) textWrapper.getChildAt(0);
String text = tv.getText().toString();
或用于多用途Spirow答案。如果您只有一个孩子,则按如下方式获得:
TextView tv = (TextView) textWrapper.getChildAt(0);
String text = tv.getText().toString();
或者多用Spirow答案。只需使用yourChildTextViewName.getText().toString()即可获得;只需使用yourChildTextViewName.getText().toString()即可获得;
