简单可靠的解决方案，只需重写此方法：

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    View v = getCurrentFocus();

    if (v != null &&
            (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) &&
            v instanceof EditText &&
            !v.getClass().getName().startsWith("android.webkit.")) {
        int scrcoords[] = new int[2];
        v.getLocationOnScreen(scrcoords);
        float x = ev.getRawX() + v.getLeft() - scrcoords[0];
        float y = ev.getRawY() + v.getTop() - scrcoords[1];

        if (x < v.getLeft() || x > v.getRight() || y < v.getTop() || y > v.getBottom())
            hideKeyboard(this);
    }
    return super.dispatchTouchEvent(ev);
}

public static void hideKeyboard(Activity activity) {
    if (activity != null && activity.getWindow() != null && activity.getWindow().getDecorView() != null) {
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(activity.getWindow().getDecorView().getWindowToken(), 0);
    }
}

这些解决方案都不适合我。我修复自动对焦的方法是：

<activity android:name=".android.InviteFriendsActivity"
 android:windowSoftInputMode="adjustPan">
    <intent-filter >
    </intent-filter>
</activity>

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);

在父版面中写入此行。。。

 android:focusableInTouchMode="true"

当按下按钮时，我使用以下代码阻止EditText窃取焦点。

addButton.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        View focused = internalWrapper.getFocusedChild();
        focused.setVisibility(GONE);
        v.requestFocus();
        addPanel();
        focused.setVisibility(VISIBLE);
    }
});

Basically, hide the edit text and then show it again. This works for me as the EditText is **not** in view so it doesn't matter whether it is showing.

You could try hiding and showing it in succession to see if that helps it lose focus.
