我在Android中有一个活动,包含两个元素:

编辑文本列表视图

当“活动”启动时,EditText立即具有输入焦点(闪烁光标)。我不希望任何控件在启动时具有输入焦点。我尝试了:

EditText.setSelected(false);
EditText.setFocusable(false);

没有运气。如何说服EditText在“活动”启动时不选择自己?


当前回答

<EditText
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:id="@+id/etComments"
    android:hint="Comments.."
    android:textSize="14dp"
    android:focusable="false"
    android:textStyle="italic"/>

其他回答

在第一个可编辑字段之前尝试以下操作:

<TextView  
        android:id="@+id/dummyfocus" 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:text="@string/foo"
        />

findViewById(R.id.dummyfocus).setFocusableInTouchMode(true);
findViewById(R.id.dummyfocus).requestFocus();

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();
}

在父布局(例如LinearLayout或ConstraintLayout)中添加标签android:focusableInTouchMode=“true”和android:focusable=“true”将解决该问题。

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

<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
to prevent the dummy from receiving focus again -->
<AutoCompleteTextView android:id="@+id/autotext"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:nextFocusUp="@id/autotext" 
    android:nextFocusLeft="@id/autotext"/>

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.
<EditText
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:id="@+id/etComments"
    android:hint="Comments.."
    android:textSize="14dp"
    android:focusable="false"
    android:textStyle="italic"/>
