大家好,当我点击按钮InputFilter filter = new InputFilter() {
public CharSequence filter(CharSequence source, int start, int end,
Spanned dest, int dstart, int dend) {
for (int i = start; i < end; i++) {
if (Character.isWhitespace(source.charAt(i))) {
return "";
}
}
return null;
}
};
editText.setFilters(new InputFilter[]{filter});
时,如何将图像上传到我的webhost上的文件管理器?截至目前,我没有开始任何事情,因为我试图按照我从图库上传的方式上传它,它没有工作。你能帮帮我们吗?截至目前,我清理了我的代码,这就是它
