Question

我有一个列表视图，当它被点击时，它将获得所有值，它应该在对话框的视图中显示。但它没有用。我怎么能这样做？

 list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {


        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {


            String stor = mylist.get(position).get("storcode");
            String code = mylist.get(position).get("code");
            String beg = mylist.get(position).get("beg");
            String del = mylist.get(position).get("del");
            String spo = mylist.get(position).get("spo");
            String end = mylist.get(position).get("end");

            new AlertDialog.Builder(checklist.this)
                  .setTitle("Sample")
                  .setView(R.layout.activity_layoutdialog)
                  .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {

                      }
                  })
                  .setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
                      @Override
                      public void onClick(DialogInterface dialog, int which) {

                      }
                  }).show();



            return true;
        }

    });

我在点击listview项目时尝试实现编辑功能。

Answer 1

在实际构建AlertDialog之前，您可以膨胀对话框的视图并为其EditTexts指定值。

LayoutInflater factory = LayoutInflater.from(this);
View dialogView = factory.inflate(R.layout.activity_layoutdialog, null);
EditText editText1 = (EditText) dialogView.findViewById(R.id. beginningstock);
editText1.setText(beg);
// etc

new AlertDialog.Builder(checklist.this)
              .setTitle("Sample")
              .setView(dialogView).show();
// etc

如何将listview的值传递给dialogbox setView
