在 Android 中剪切、复制、粘贴

发布于 2024-11-10 18:42:13 字数 286 浏览 5 评论 0原文

我想在我的 EditText 中实现剪切、复制、粘贴功能，我尝试使用以下代码：

    ClipMan = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
    editbox1.setText(ClipMan.getText());

用于粘贴文本，但它将整个文本粘贴到另一个编辑框中。我想复制所选文本并将该文本粘贴到相同的编辑框就像普通记事本一样工作..

非常感谢任何建议... 谢谢！！

I want to implement the cut,copy, paste functionality in my EditText,i tried with the following code :

    ClipMan = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
    editbox1.setText(ClipMan.getText());

for paste the text,but it paste the whole text in another Editbox..I want to copy the selected text and paste that text in the same Editbox just like the normal notepad works..

Any suggestions are greatly appreciated...

要复制数据

ClipData clip = ClipData.newPlainText("simple text",Value);
ClipMan.setPrimaryClip(clip);

并获取在您的情况下复制的数据，

CharSequence pasteData="";
ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
pasteData = item.getText();

您可以使用 EditText.getText() 而不是 Value 。
和 EditText.setText(pasteData); 用于粘贴该数据。

for copy data

ClipData clip = ClipData.newPlainText("simple text",Value);
ClipMan.setPrimaryClip(clip);

and get data which was copied

CharSequence pasteData="";
ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
pasteData = item.getText();

in your case you can use EditText.getText() instead of Value..
and EditText.setText(pasteData); for paste that data.

最后，我可以在我的应用程序中复制、粘贴。现在我可以使用以下代码仅粘贴选定的文本：

Editable s1;
EditText editbox2;

复制选定的文本：

       if(editbox2.getSelectionEnd() > editbox2.getSelectionStart()) 
        {
            s1 = (Editable) editbox2.getText().subSequence(editbox2.getSelectionStart(), editbox2.getSelectionEnd());
        }else
        {
            s1 = (Editable) editbox2.getText().subSequence(editbox2.getSelectionEnd(), editbox2.getSelectionStart());
        }

粘贴选定的文本：

             editbox2.getText().replace(Math.min(editbox2.getSelectionStart(),editbox2.getSelectionEnd()), Math.max(editbox2.getSelectionStart(), editbox2.getSelectionEnd()),s1, 0, s1.length());

Finally i am able to copy ,paste in my application..now i can paste only selected text by using this code :

Editable s1;
EditText editbox2;

to copy the selected text :

       if(editbox2.getSelectionEnd() > editbox2.getSelectionStart()) 
        {
            s1 = (Editable) editbox2.getText().subSequence(editbox2.getSelectionStart(), editbox2.getSelectionEnd());
        }else
        {
            s1 = (Editable) editbox2.getText().subSequence(editbox2.getSelectionEnd(), editbox2.getSelectionStart());
        }

to paste the selected text:

             editbox2.getText().replace(Math.min(editbox2.getSelectionStart(),editbox2.getSelectionEnd()), Math.max(editbox2.getSelectionStart(), editbox2.getSelectionEnd()),s1, 0, s1.length());

我们可以这样做：

    int min2 = 0;
    int max2 = editText.getText().length();
    if (editText.isFocused()) {
        final int selStart = editText.getSelectionStart();
        final int selEnd = editText.getSelectionEnd();

        min2 = Math.max(0, Math.min(selStart, selEnd));
        max2 = Math.max(0, Math.max(selStart, selEnd));
     }
     ClipData abc = myClipboard.getPrimaryClip();
     ClipData.Item item = abc.getItemAt(0);

     String text = item.getText().toString();
     editText.getText().replace(min2,max2 , text);

we can do this way :

    int min2 = 0;
    int max2 = editText.getText().length();
    if (editText.isFocused()) {
        final int selStart = editText.getSelectionStart();
        final int selEnd = editText.getSelectionEnd();

        min2 = Math.max(0, Math.min(selStart, selEnd));
        max2 = Math.max(0, Math.max(selStart, selEnd));
     }
     ClipData abc = myClipboard.getPrimaryClip();
     ClipData.Item item = abc.getItemAt(0);

     String text = item.getText().toString();
     editText.getText().replace(min2,max2 , text);
