View current = getCurrentFocus();

if (current != null) 
    current.clearFocus();

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.

是的，我做了同样的事情——创建一个“虚拟”线性布局，以获得初始焦点。此外，我设置了“下一个”焦点ID，这样用户在滚动一次后就不能再聚焦了：

<LinearLayout 'dummy'>
<EditText et>

dummy.setNextFocusDownId(et.getId());
 
dummy.setNextFocusUpId(et.getId());
 
et.setNextFocusUpId(et.getId());

很多工作只是为了摆脱对视图的关注。

谢谢

利用其他海报提供的信息，我使用了以下解决方案：

在布局XML中

<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
    android:id="@+id/linearLayout_focus"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:layout_width="0px"
    android:layout_height="0px"/>

<!-- AUTOCOMPLETE -->
<AutoCompleteTextView
    android:id="@+id/autocomplete"
    android:layout_width="200dip"
    android:layout_height="wrap_content"
    android:layout_marginTop="20dip"
    android:inputType="textNoSuggestions|textVisiblePassword"/>

在onCreate（）中

private AutoCompleteTextView mAutoCompleteTextView;
private LinearLayout mLinearLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mylayout);

    //get references to UI components
    mAutoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
    mLinearLayout = (LinearLayout) findViewById(R.id.linearLayout_focus);
}

最后，在onResume（）中

@Override
protected void onResume() {
    super.onResume();

    //do not give the editbox focus automatically when activity starts
    mAutoCompleteTextView.clearFocus();
    mLinearLayout.requestFocus();
}
