Question

我正在尝试使用包含Autocompletetextview的片段构建android应用程序，我想在显示片段时显示键盘。我尝试了很少但却没有成功。

这是我的代码

XML

<AutoCompleteTextView
    android:id="@+id/editArea"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:completionThreshold="1"
    android:singleLine="true"
    android:textColor="@android:color/primary_text_light" 
    android:gravity="right" >
</AutoCompleteTextView>

我的Java片段

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    mLayout = inflater.inflate(R.layout.change_area, null, false);
    area = (AutoCompleteTextView) mLayout.findViewById(R.id.editArea);
    showHideKeyboard(true);
    citiesList = singleToneCitiesList.getInstance().getList();


    mAdapter = new CitiesAdapter(getActivity(),
            R.layout.autocommplete_text, citiesList);
    area.setAdapter(mAdapter);
    area.setThreshold(1);
    area.setOnItemClickListener(this);
    return mLayout;
}



private void showHideKeyboard(boolean showHide) {
    if (showHide) {
        InputMethodManager inputMethodManager = (InputMethodManager) getActivity()
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        area.requestLayout();

        if (inputMethodManager != null) {
            inputMethodManager.toggleSoftInputFromWindow(getActivity()
                    .getCurrentFocus().getApplicationWindowToken(),
                    InputMethodManager.SHOW_FORCED, 0);
        }

    } else {
        InputMethodManager imm = (InputMethodManager) getActivity()
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(area.getWindowToken(), 0);

    }
}

Answer 1

在xml代码中使用它：

 <AutoCompleteTextView
    android:id="@+id/editArea"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:completionThreshold="1"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:gravity="right"
    android:singleLine="true"
    android:textColor="@android:color/primary_text_light" >

    <requestFocus />
  </AutoCompleteTextView>

并在清单中的活动中添加以下内容：

android:windowSoftInputMode="stateAlwaysVisible"

Answer 2

你需要像这样请求焦点

AutoCompleteTextView yourView = findViewById(R.id.your_id);
yourView.requestFocus();

Answer 3

通过代码编辑requestFocus(); AutoCompleteTextView，

autocomplete.requestFocus();

或者你也可以在xml中设置。

Autocompletetextview显示键盘不起作用
