從警報對話框設置文本

Question

這是我的代碼：

AlertDialog.Builder alert = new AlertDialog.Builder(this);

            alert.setTitle("What's Your name?");
            alert.setMessage("Seems like you're new here! What's your name?");

            // Set an EditText view to get user input 
            final EditText input = new EditText(this);
            alert.setView(input);

            alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {

              }
            });

            alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int whichButton) {
                // Canceled.
              }
            });

這將打開一個帶有確定和取消按鈕的編輯文本。

當您單擊確定時，我該怎么做，它將把TextView的文本更改為框內的內容

Answer 1

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                 String newText = input.getText().toString();
                 textView.setText(newText);
            }
});
