我有一个ListView,每行包含两个TextView和一个EditText。我搜索并搜索过,无法弄清楚如何获取用户输入EditText的文本。我最近的尝试实现了TextWatcher。
public void addIngredientToMeal(String ingredientName) {
ingredient_list = (ListView) findViewById(R.id.ingredients_in_meal_listView);
int numberOfIngredients = ingredient_list.getChildCount();
ListAdapter adapter = new ListAdapter();
adapter.name_array = new String[numberOfIngredients+1];
for (int i = 0; i < numberOfIngredients; i++)
adapter.name_array[i] = (String) ingredient_list.getItemAtPosition(i);
adapter.name_array[numberOfIngredients] = ingredientName;
ingredient_list.setItemsCanFocus(true);
ingredient_list.setAdapter(adapter);
}
private class ListAdapter extends BaseAdapter{
public String[] name_array, qty_array;
@Override
public int getCount() {
// TODO Auto-generated method stub
if(name_array != null && name_array.length != 0){
return name_array.length;
}
return 0;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return name_array[position];
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
//ViewHolder holder = null;
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
LayoutInflater inflater = NewMeal.this.getLayoutInflater();
convertView = inflater.inflate(R.layout.ingredients_in_meal_layout, null);
holder.textView1 = (TextView) convertView.findViewById(R.id.ingredient_name_in_new_meal_textView);
holder.editText1 = (EditText) convertView.findViewById(R.id.ingredient_qty_in_new_meal_editText);
holder.textView2 = (TextView) convertView.findViewById(R.id.ingredient_unit_in_new_meal_textView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.ref = position;
holder.textView1.setText(name_array[position]);
holder.textView2.setText(databaseAdapter.dbQuery(name_array[position]));
holder.editText1.setText(qty_array[position]);
holder.editText1.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
qty_array[holder.ref] = arg0.toString();
}
});
return convertView;
}
private class ViewHolder {
TextView textView1, textView2;
EditText editText1;
int ref;
}
}
}
答案 0 :(得分:5)
对于那些可能有类似问题的人,我解决了我遇到的问题。
问题: 需要获取在listView中包含的多个editTexts中输入的值。使用listviewname.getItemAtPosition(整数)只获取第一个editText的值。此外,我在listview的每一行中都包含多个视图,因此getItemAtPosition仅返回listView第一行中第一个视图的值。
解决方案:
这里有一些可以在按下按钮时实现的示例代码:
ListView lvName = (ListView) findViewById(R.id.listview1);
View v;
EditText et;
int listLength = lv.getChildCount();
String[] valueOfEditText = new String(listLength);
for (int i = 0; i < listLength; i++)
{
v = lvName.getChildAt(i);
et = (EditText) v.findViewById(R.id.edittext1);
valueOfEditText[i] = et.getText().toString();
}
答案 1 :(得分:0)
getFocusedChild(position)它将返回一个View或findFocus()
View row = ingredient_list.getFocusedChild();
EditText et = (EditText)row.findViewById(R.id.ingredient_qty_in_new_meal_editText);
