android - ExpandableListView onChildClickListener

Question

我是安卓新手。

我在使用 ExpandableListViewAdapter 时遇到了问题。

当我点击编辑文本框时，onChildClickListener 不工作。

我的问题是它是否适用于编辑文本框。

我正在实现 BaseExpandableListAdapter。

提前致谢。

public class TryExpandableListViewActivity extends Activity implements     OnChildClickListener {

LinearLayout llayout;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    llayout = (LinearLayout) findViewById(R.id.llayout);

    ExpandableListView list = new ExpandableListView(this);
    list.setGroupIndicator(null);
    list.setChildIndicator(null);
    String[] titles = {"A","B","C"};
    String[] fruits = {"a1","a2"};
    String[] veggies = {"b1","b2","b3"};
    String[] meats = {"c1","c2"};
    String[][] contents = {fruits,veggies,meats};
    SimplerExpandableListAdapter adapter = new SimplerExpandableListAdapter(this,titles, contents);

    list.setAdapter(adapter);

    llayout.addView(list);

    list.setOnChildClickListener(this);
}

@Override
public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
    Log.i("Test","-------------------------------------------");
    return false;
}

class SimplerExpandableListAdapter extends BaseExpandableListAdapter {

private Context mContext;
private String[][] mContents;
private String[] mTitles;

public SimplerExpandableListAdapter(Context context, String[] titles, String[][] contents) {
    super();
    if(titles.length != contents.length) {
      throw new IllegalArgumentException("Titles and Contents must be the same size.");
    }
    mContext = context;
    mContents = contents;
    mTitles = titles;

  }

@Override
public Object getChild(int groupPosition, int childPosition) {
    return mContents[groupPosition][childPosition];
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return 0;
}

@Override
public View getChildView(int groupPosition, int childPosition,
    boolean isLastChild, View convertView, ViewGroup parent) { 

        EditText row = (EditText)convertView;
        if(row == null) {
          row = new EditText(mContext);
        }
        row.setTypeface(Typeface.DEFAULT_BOLD);
        row.setText(mContents[groupPosition][childPosition]);
        return row;

}

@Override
public int getChildrenCount(int groupPosition) {
    return mContents[groupPosition].length;
}

@Override
public Object getGroup(int groupPosition) {
    return mContents[groupPosition];
}

@Override
public int getGroupCount() {
    return mContents.length;
}

@Override
public long getGroupId(int groupPosition) {
    return 0;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
    View convertView, ViewGroup parent) {
    TextView row = (TextView)convertView;
    if(row == null) {
      row = new TextView(mContext);
    }
    row.setTypeface(Typeface.DEFAULT_BOLD);
    row.setText(mTitles[groupPosition]);
    return row;
}

@Override
public boolean hasStableIds() {
    return false;
}

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    return true;
}

在没有看到代码的情况下，这只是一个猜测，但是 childCLickListener 可能正在使用该事件，因此它没有到达编辑文本，请尝试在 childClickListener 中返回 false

好吧，我刚刚用您的代码创建了一个小项目，但我无法触发 onCildClickListener，将其更改为 TextView 后效果很好。它与 EditText 有关(可能是它消耗了事件，或者它没有注册为点击，而是注册为焦点的变化，但我只是在猜测这一点)。

所以在回答您的问题时，是否可能 - 我认为不可能。但我确实做了一个可能有用的小解决方法。

将 onTouchListener() 附加到 EditText 并检查 MotionEvent.ACTION_DOWN
