从警报对话框设置文本

Question

这是我的代码：

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.
              }
            });

这将打开一个带有确定和取消按钮的编辑文本。

当您单击确定时，我该怎么做，它将把TextView的文本更改为框内的内容

Answer 1

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