为ListAdapter项打开软键,其中包含带字符串的视图

Question

我有一个ListAdapter,在这种情况下包含一个项目.该项生成一个具有EditText的视图.

当视图显示时,我想打开软键盘以允许用户编辑该字段.

我试着调用适配器的getView()函数:

View edittext = view.findViewById(R.id.EditText01);
edittext.requestFocus();
mInputMgr.showSoftInput(edittext, InputMethodManager.SHOW_FORCED);

这似乎没有做任何事情.

我也尝试过:

View edittext = view.findViewById(R.id.EditText01);
edittext.requestFocus();
mInputMgr.toggleSoftInput(0, 0);

这产生了一个神秘的原因,一个循环,其中软键盘可重复打开和关闭.

当我删除requestFocus并触摸点击程序中的EditText时,它会弹出软键盘,但是看看requestFocus是否存在,showSoftInput似乎不起作用.

我需要做什么？

list元素的XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:orientation="vertical"
  android:layout_height="fill_parent"

  android:focusable="true"
  android:background="@color/light_blue"
  >

<EditText android:id="@+id/EditText01" 
android:layout_height="wrap_content" 
android:text="" 
android:focusable="true"
android:layout_width="fill_parent" android:inputType="textShortMessage"></EditText>
</RelativeLayout>

包含ListView的XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:orientation="vertical"
  android:layout_height="fill_parent"
  >
    <Button android:text="@+id/Button01" 
        android:id="@+id/Button01" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"/>
    <ListView android:id="@+id/ListView01" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:layout_below="@+id/Button01"
        android:gravity="center_horizontal"
        />
</RelativeLayout>

long getView函数:

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    if (convertView != null){
        return convertView;
    }

    if (mDialog!=null){
        final Choice thisChoice = mDialog.getChoice(
                position, 
                mContentRes);
        Log.v(TAG, "DialogAdapter: "+ thisChoice.toString());

        View view = thisChoice.getView(
                mInflater, parent, mFillInput, mDialog);
        View.OnClickListener listener = new View.OnClickListener() {
            public void onClick(View v) {
                if (thisChoice.choiceSingleClick(mDialog)){
                    Log.i(TAG, 
                            "Single Click selected Choice: " 
                            + thisChoice.toString());
                    Log.d(TAG, 
                            "getNextInputId: " 
                            + Integer.toString(
                                    thisChoice.getNextInputId()));
                    mFillInput.renderNext(thisChoice.getNextInputId());
                }
                else{
                    mFillInput.checkSelectedStatus();
                }
            }
        };
        view.setOnClickListener(listener);

        View.OnLongClickListener longListener = new View.OnLongClickListener() {
            public boolean onLongClick(View v) {            
                thisChoice.choiceLongClick(mDialog);
                return false;
            }
        };
        view.setOnLongClickListener(longListener);

        Log.d(TAG, "thisChoice: " + thisChoice);
        Log.d(TAG, "selected: " + thisChoice.isSelected());
        if((position == 0 && mDialog.getSelectedCount() == 0) ||
                thisChoice.isSelected()){
            view.requestFocus();
        }


        if (thisChoice.isEnterStringChoice() & position==0){
            Log.d(TAG, "Request Focus for StringChoice");
            View edittext = view.findViewById(R.id.EditText01);
            edittext.requestFocus();
            //edittext.dispatchTouchEvent(null);
            //FillInput.mInputMgr.showSoftInput(edittext, InputMethodManager.SHOW_FORCED);
            //mFillInput.mInputMgr.toggleSoftInput(0, 0);
        }

        return view;
    }           
    else{
        return null;
    }
}

尝试在 TextEdit 控件上的android:focusable="true"xml 或 java 代码中进行设置setFocusable(true)
