Question

我有一个自定义listView，每行都有editText来携带用户输入的值。我在listview旁边有一个按钮，onclick将从列表中的所有行中添加editText值。

任何人都可以给我一些链接以获取一些线索。

        }

    }

    void setParent(NRSessionFragmentHolder parent) {

    }

    public int valueReturn(String[] dummyVal, EditText period2,
            ListView parentList) {
        Integer add = 0;
        for (int i = 0; i <= dummyVal.length; i++) {
            View temp = null;
            temp = parentList.getChildAt(i);
            while (!(temp == null)) {
                add = Integer.parseInt(period2.getText().toString());

            }
        }
        return add;
    }

}

Answer 1

嘿我找到了一种方法来做到这一点......事实证明这很简单....这里是代码....这里我使用ListView来代替值....

 parentList=(ListView)findViewByid(R.id.list);

 public int getTvValue() {
    View view;
    String[] edVal = new String[parentList.getChildCount()];
    int val = 0;
    for (int i = 0; i < parentList.getCount(); i++) {
        view = parentList.getChildAt(i);
        TextView tv = (TextView) view.findViewById(R.id.TVmid);
        edVal[i] = tv.getText().toString();
        val = Integer.parseInt(edVal[i]) + val;
    }
    return val;

}

你需要你的Button onClickListener()来获取listView的适配器，将它转换为List并总结列表的内容。
