Question

我在ListView中有Fragment，我需要能够检测到ListView中的某个项目何时被选中。我需要列表项来沿这些行抛出一个标记或类似的内容，以便包含Fragments的Main Activity中的方法可以检测ListView是否被操作。我需要主活动中的方法基本上像这样：

public void doSomething(){
    if(Fragment ListView onItemClick is detected){
        //--- do something
    } else {
        //--- don't do anything
    }
}

片段ListView中的OnItemClickListener需要表明它已被采取行动，如下所示：

list_LV.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Cursor getPathCursor = (Cursor) list_LV.getItemAtPosition(position);               
        String cursorSDFStr = getPathCursor.getString(getPathCursor.getColumnIndexOrThrow("sdfdate"));
        String cursorCalDateStr = getPathCursor.getString(getPathCursor.getColumnIndexOrThrow("caldate"));
        String cursorURLStr = getPathCursor.getString(getPathCursor.getColumnIndexOrThrow("path"));
        String cursorTitleStr = getPathCursor.getString(getPathCursor.getColumnIndexOrThrow("title"));
        String cursorbodyStr = getPathCursor.getString(getPathCursor.getColumnIndexOrThrow("body"));

        Intent slpI = new Intent("com.myapp.LISTVIDEO");
        slpI.putExtra("SDFKey", cursorSDFStr);
        slpI.putExtra("CalDateKey", cursorCalDateStr);
        slpI.putExtra("PathKey", cursorURLStr);
        slpI.putExtra("TitleKey", cursorTitleStr);
        slpI.putExtra("bodyKey", cursorbodyStr);
        startActivity(slpI);
    }
});
