做这个，完成你的工作！

android:focusable="true"
android:focusableInTouchMode="true"

对我来说，在所有设备上工作的是：

    <!-- fake first focusable view, to allow stealing the focus to itself when clearing the focus from others -->

    <View
    android:layout_width="0px"
    android:layout_height="0px"
    android:focusable="true"
    android:focusableInTouchMode="true" />

只需将此作为一个视图放在有问题的聚焦视图之前，就可以了。

最迟但最简单的答案，只需将其添加到XML的父布局中即可。

android:focusable="true" 
android:focusableInTouchMode="true"

由于我不喜欢用与功能相关的东西来污染XML，所以我创建了这个方法，它“透明地”从第一个可聚焦视图中窃取焦点，然后确保在必要时删除它自己！

public static View preventInitialFocus(final Activity activity)
{
    final ViewGroup content = (ViewGroup)activity.findViewById(android.R.id.content);
    final View root = content.getChildAt(0);
    if (root == null) return null;
    final View focusDummy = new View(activity);
    final View.OnFocusChangeListener onFocusChangeListener = new View.OnFocusChangeListener()
    {
        @Override
        public void onFocusChange(View view, boolean b)
        {
            view.setOnFocusChangeListener(null);
            content.removeView(focusDummy);
        }
    };
    focusDummy.setFocusable(true);
    focusDummy.setFocusableInTouchMode(true);
    content.addView(focusDummy, 0, new LinearLayout.LayoutParams(0, 0));
    if (root instanceof ViewGroup)
    {
        final ViewGroup _root = (ViewGroup)root;
        for (int i = 1, children = _root.getChildCount(); i < children; i++)
        {
            final View child = _root.getChildAt(i);
            if (child.isFocusable() || child.isFocusableInTouchMode())
            {
                child.setOnFocusChangeListener(onFocusChangeListener);
                break;
            }
        }
    }
    else if (root.isFocusable() || root.isFocusableInTouchMode())
        root.setOnFocusChangeListener(onFocusChangeListener);

    return focusDummy;
}

隐藏键盘的最简单方法是使用setSoftInputMode

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

或者可以使用InputMethodManager并像这样隐藏键盘。

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

在onCreate方法中添加以下内容：

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
