我写了一个Listview如下：
ListView shourulv = (ListView) findViewById(R.id.shourulv);
List<HashMap<String, Object>> data1 = new ArrayList<HashMap<String, Object>>();
for (Outcome outcome1 : outcomes)
{
HashMap<String, Object> item1 = new HashMap<String, Object>();
item1.put("outcomeid", outcome1.getOutcomeid());
item1.put("name1", outcome1.getName1());
item1.put("money1", outcome1.getMoney1());
item1.put("message1", outcome1.getMessage1());
item1.put("time1", outcome1.getTime1());
data1.add(item1);
}
// 适配器的选择
SimpleAdapter adapter = new SimpleAdapter(MingxiActivity.this, data1, R.layout.item, new String[]
{ "outcomeid", "name1", "money1", "message1", "time1" }, new int[]
{ R.id.iditem, R.id.namesr, R.id.moneysr, R.id.messagesr, R.id.timesr });
shourulv.setAdapter(adapter);
// 为ListView添加点击事件
shourulv.setOnItemClickListener(new OnItemClickListener
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
ListView lView = (ListView) parent
HashMap<String, Object> item3 = (HashMap<String, Object>) lView.getItemAtPosition(position);
String a=Stirng.valueOf(item3.get(outcomeid));
dialog(a);
}
});
对话框如下：
protected void dialog1(final Integer outcomeid5)
{
AlertDialog.Builder builder = new Builder(MingxiActivity.this);
builder.setMessage("你选择的是？");
builder.setTitle("欢迎");
builder.setPositiveButton("删除", new
android.content.DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.dismiss();
outcometable.delete(outcomeid5);
}
});
builder.setNegativeButton("修改", new
android.content.DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int which)
{
dialog.dismiss();
}
});
builder.create().show();
}
删除数据方法如下：
public void delete(String id )
{
SQLiteDatabase db = financialManagementSystemData.getWritableDatabase();
db.execSQL("delete from outcome where outcomeid=? ", new Object[]
{ id.toString()});
}
问题是我点击删除按钮时出错了，请问问题出现在哪里？
------解决方案--------------------
报什么错了？把异常信息贴出来？
------解决方案--------------------
dialog.dismiss();//删掉
outcometable.delete(outcomeid5);
------解决方案--------------------
不把异常公布出来谁知道是哪里错误啊
------解决方案--------------------
SimpleAdapter可以用自定义id?
可以参照这个帖子，可以帮到你。
