Question

ANDROID listview 点击其中的imageView修改 listview的值

view = LayoutInflater.from(getContext()).inflate(R.layout.todolist_element, null);
final TextView textView = (TextView) view.findViewById(R.id.drag_item);
textView.setText(getItem(position));
textView.setTextSize(30);
//弹出框edittext
final EditText itemEditText = new EditText(getContext());
ImageView itemEditImg = (ImageView) view.findViewById(R.id.drag_item_edit);
//弹出对话框
itemEditImg.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
new AlertDialog.Builder(getContext())
.setTitle(R.string.edit)
.setView(itemEditText)
.setPositiveButton("确定", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface arg0,int arg1) {
System.out.println("*****"+itemEditText.getText());
input = itemEditText.getText().toString();
//textView.setText(itemEditText.getText().toString());
if(isNullOrEmpty(input)){
System.out.println("!!!空");
}else{
System.out.println("!!!"+input);
textView.setText(input);
}
}
})
.setNegativeButton("取消", null)
.show();
}
});

这个是我写在adapter的getView()里面的，但是 textView.setText(input);这个不管用的，sysout都打印出来edittext中输入的值了，就是set不进去，如果不用弹出的对话框，就可以成功set值进去

Answer 1

final TextView textView = (TextView) view.findViewById(R.id.drag_item); 里边的final能去了么

Answer 2

notifyDataSetChanged()下试试
