EditText上的Done按钮的监听器？ [英] Listener for Done button on EditText?

问题描述

如果我有一个EditText并且我想听用户是否按下键盘上的完成按钮..我该怎么做？

If I have an EditText and I want to listen for if the user presses the "done" button on the keypad.. how would I do this?

推荐答案

代码是

final EditText edittext = (EditText) findViewById(R.id.edittext);
edittext.setOnKeyListener(new View.OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
                Toast.makeText(HelloFormStuff.this, edittext.getText(), Toast.LENGTH_SHORT).show();
                return true;
            }
            return false;
        }
    });

在'edittext'中是textfield的id

In that 'edittext' is id of textfield

请查看此链接只需将setOnKeyListener设置为您的editText
