我在我的应用程序中使用“编辑文本”字段。当我单击它时，会出现软键盘。但是，当我单击“完成”按钮（位于软键盘上）时，它应该消失但不会消失。我将输入类型设置为布局文件中的文本。我想在按下按钮时隐藏软键盘。
请帮忙。谢谢。
这是我的代码。

最佳答案
我使用此功能：
public static void hideSoftInput(Context ctx)
{
InputMethodManager inputManager = (InputMethodManager) ctx.getSystemService(INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(new View(ctx).getWindowToken(), 0);
}
对于您的特定情况，可以使用以下方法：
location_entered.setOnKeyListener(new View.OnKeyListener()
{
@Override
public boolean onKey(View v, int keyCode, KeyEvent event)
{
if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)
{
// code to hide the soft keyboard
InputMethodManager imm = (InputMethodManager) getSystemService(
Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getApplicationWindowToken(), 0);
}
return false;
}
});
在onCreate的这一部分之后：
location_entered.setOnClickListener(new View.OnClickListener() {
[...]
