通过按钮从其他和过去的EditText视图复制

问题描述

我复制了另一个网站的链接，并希望通过Android中的按钮将复制的文本传递到EditText字段中。

解决方法

要从剪贴板中获取数据并将其粘贴到您的EditText中，请执行以下操作：

// get a reference to the ClipboardManager
ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
// you will save the text in here later
String pasteData = "";

// Examines the item on the clipboard. If getText() does not return null,the clip item contains the
// text. Assumes that this application can only handle one item at a time.
 ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);

// Gets the clipboard as text.
pasteData = item.getText();

// If the string contains data,then the paste operation is done
if (pasteData != null) {
    return true;

// The clipboard does not contain text. If it contains a URI,attempts to get data from it
} else {
    Uri pasteUri = item.getUri();

    // If the URI contains something,try to get text from it
    if (pasteUri != null) {

        // calls a routine to resolve the URI and get data from it. This routine is not
        // presented here.
        pasteData = resolveUri(Uri);
        return true;
    } else {

        // Something is wrong. The MIME type was plain text,but the clipboard does not contain either
        // text or a Uri. Report an error.
        Log.e(TAG,"Clipboard contains an invalid data type");
        return false;
    }
}

// make sure you have gotten any text and then set in your edittext
if (pasteData != null && !pasteData.isEmpty()) {
    editText.setText(pasteData)
}
