如何在编辑文本聚焦时显示软键盘

问题描述

我想在 EditText 聚焦时自动显示软键盘(如果设备没有物理键盘)，我有两个问题:

I want to automatically show the soft-keyboard when an EditText is focused (if the device does not have a physical keyboard) and I have two problems:

1. 当我的 Activity 显示时，我的 EditText 被聚焦但没有显示键盘，我需要再次点击它以显示键盘(它应该在显示我的 Activity 时显示).

1. When my Activity is displayed, my EditText is focused but the keyboard is not displayed, I need to click again on it to show the keyboard (it should be displayed when my Activity is displayed).

当我在键盘上点击完成时，键盘被关闭，但 EditText 保持聚焦并且你不想要(因为我的编辑已经完成).

And when I click done on the keyboard, the keyboard is dissmissed but the EditText stays focused and y don't want (because my edit is done).

继续，我的问题是在 iPhone 上有一些更像的东西:它使键盘与我的 EditText 状态(聚焦/不聚焦)保持同步，当然不会出现软键盘如果有实体的话.

To resume, my problem is to have something more like on the iPhone: which keep the keyboard sync with my EditText state (focused / not focused) and of course does not present a soft-keyboard if there is a physical one.

推荐答案

要强制出现软键盘，可以使用

To force the soft keyboard to appear, you can use

EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
yourEditText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);

为了移除 EditText 上的焦点，遗憾的是你需要一个虚拟的 View 来获取焦点.

And for removing the focus on EditText, sadly you need to have a dummy View to grab focus.

要关闭它，您可以使用

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(yourEditText.getWindowToken(), 0);

这适用于在对话框中使用它

This works for using it in a dialog

public void showKeyboard(){
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

public void closeKeyboard(){
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}
