Question

我想在EditText中选择一些文本，它是ListView的子元素。必须在剪贴板上设置所选文本。我无法找到任何关于此的例子。我该怎么办呢？ selectionStart和selectionEnd不适用于此。感谢。

Answer 1

这是可能的解决方案。在listview的getView方法中执行以下操作：

enter code here:

public View getView(final int position, View convertView, ViewGroup parent) {
            // A ViewHolder keeps references to children views to avoid unneccessary calls
            // to findViewById() on each row.
            final ViewHolder holder;


            if (convertView == null) {
                convertView = mInflater.inflate(R.layout.main, null);

                // Creates a ViewHolder and store references to the two children views
                // we want to bind data to.
                holder = new ViewHolder();


                holder.subText = (TextView) convertView.findViewById(R.id.subTxt);      

                convertView.setTag(holder);
            } else {
                // Get the ViewHolder back to get fast access to the TextView
                // and the ImageView.
                holder = (ViewHolder) convertView.getTag();
            }

            //TEXT BOX position is 0 then 
            if(position == 0) {

                ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); clipboard.setText(txtEdit.getText().toString());
            } 
            return convertView;
        }

Answer 2

在列表选择事件

上使用此代码

ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); clipboard.setText(txtEdit.getText().toString());

Answer 3

EditText已经在长按时提供了这个功能....意味着按下editText上的长按，弹出上下文菜单，询问全选，选择文本，全部复制。

Answer 4

您可以在editText长按事件inlistView自定义适配器上打开一个对话框，并显示两个选项复制并粘贴到其中

您可以使用

以编程方式复制文本

ClipboardManager clipboard = 
                              (ClipboardManager) c1.getSystemService(c1.CLIPBOARD_SERVICE); 

                         clipboard.setText("Text to copy");

并使用

获取文本

System.out.println(clipboard.getText());

Answer 5

InputConnection ic = getCurrentInputConnection();
ExtractedText extracted = ic.getExtractedText(
                    new ExtractedTextRequest(), 0);
            /*If selection start and end are not equal then selected text 
             * needs to be deleted and updated to core*/
            if (extracted!= null && extracted.selectionStart != extracted.selectionEnd) {
}

使用ExtractedText提供的api
