.el-time-spinner__wrapper .el-scrollbar__wrap:not(.el-scrollbar__wrap--hidden-default) { padding-bottom: 0; }

这是一个 CSS 样式代码块,定义了一个选择器 `.el-time-spinner__wrapper .el-scrollbar__wrap:not(.el-scrollbar__wrap--hidden-default)`,该选择器应用于某个元素。该代码块为符合该选择器的元素设置了 `padding-bottom: 0`,即将其底部的内边距设置为 0。在 HTML 页面中,如果存在类名为 `.el-time-spinner__wrapper` 的元素,并且该元素包含了一个类名为 `.el-scrollbar__wrap` 且没有 `.el-scrollbar__wrap--hidden-default` 类名的子元素,则该子元素的底部内边距将被设置为 0。这个代码块的作用可能是为了微调该元素的布局,使其更加美观和符合设计要求。需要注意的是,该代码块可能会被其他 CSS 样式所覆盖,因此具体的效果还需要根据实际情况进行调试和确认。

这个错误是由于你在 Spinner 上使用了 `setOnItemClickListener` 方法,而这个方法不能用于 Spinner。Spinner 是一个下拉列表,你应该使用 `setOnItemSelectedListener` 方法来监听 Spinner 中选择的项目。请检查你的代码中是否有类似以下的代码:
```java
spinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// do something
}
});
```
将其替换为以下代码:
```java
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// do something
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
// do something
}
});
```
这样应该可以解决你遇到的问题。

private EditText mEditItemTime;
private EditText mEditItemLocation;
private TextView mTextImagePath;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

// 初始化控件
mSpinnerLostFound = findViewById(R.id.spinner_lost_found);
mEditItemName = findViewById(R.id.edit_item_name);
mEditItemDesc = findViewById(R.id.edit_item_desc);

mButtonUploadImage = findViewById(R.id.button_upload_image);
mButtonSubmit = findViewById(R.id.button_submit);
mImagePicker = new ImagePicker(this); // 创建文件选择器
// 设置上传图片按钮点击事件
mButtonUploadImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mImagePicker.choosePicture(true /* allow camera */);
}
});
// 设置提交按钮点击事件
mButtonSubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO: 实现数据提交逻辑
}
});
}
// 在Activity中添加以下两个方法以便与文件选择器交互
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mImagePicker.handleActivityResult(requestCode, resultCode, data);
}
