TextView相关

实现出现字符省略号

TextView自带的可以通过 android:ellipsize="end" android:singleLine="true"

android:maxWidth="90dp"

判断是否有省略号

    private void hideExpondBoxWhenNoellipsized(TextView tv, View cb) {
        if(tv == null || cb == null){
            return;
        }
        Layout l = tv.getLayout();
        if (l != null) {
            int lines = l.getLineCount();
            if (lines > 0) {
                if (l.getEllipsisCount(lines - 1) > 0) {
                    // Log.d("", "Text is ellipsized"+lines);
                    // tv.setEllipsize(null);
                    cb.setVisibility(View.VISIBLE);
                } else {
                    // Log.d("", "Text is not ellipsized"+lines);
                    // tv.setEllipsize(TextUtils.TruncateAt.END);
                    cb.setVisibility(View.GONE);
                }
            }
        }
    }
