解雇键盘ACTION_DONE preSS的Andr​​oid preferences对话框 [英] Dismiss android preferences dialog on Keyboard ACTION_DONE press

问题描述

我希望能够关闭编辑preference对话框（如下图所示 http://twitpic.com / 18ttdp ）由pressing键盘上的完成按钮。

I would like to be able to close the editpreference dialog (as shown here http://twitpic.com/18ttdp) by pressing the 'Done' button on the keyboard.

目前，完成pressing刚刚驳回了键盘，但离开对话框。

Currently, pressing 'Done' just dismisses the keyboard but leaves the dialog.

在我的应用程序的其他部分我使用类似code以下拦截完成键preSS和我的活动执行动作：

In other parts of my application I use code similar to the following to intercept the 'Done' key press and execute actions in my activity:

text.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_DONE) {
                //do stuff here
                return true;
            }
            return false;
        }
    });

不过，我不确定如何做到实现我的preference活动或布局XML这个同样的效果。

However, I am unsure of how to do achieve this same effect in my preference activity or layout xml.

推荐答案

下面是我如何解决它：

    final EditTextPreference namePref = (EditTextPreference) findPreference("name");
    namePref.getEditText().setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if(actionId == EditorInfo.IME_ACTION_DONE) {
                namePref.onClick(null, DialogInterface.BUTTON_POSITIVE);
                namePref.getDialog().dismiss();
                return true;
            }
            return false;
        }
    });

但你可能要考虑继承的EditText preference代替，因为这的onClick调用是一个黑客，它的实现可能在未来改变。

But you may want to consider subclassing EditTextPreference instead, since this onClick call is a hack, and its implementation may change in the future.
