我在活动A中有一个listView
,如下所示。
点击第一个列表后,它应在3
上显示editText
。但它显示5
实际上从最后一个列表中获取。
活动A
ArrayAdapter<String> adapter;
ArrayList<String> m_listItems = new ArrayList<String>();
int mClickedPosition;
adapter=new ArrayAdapter<String (getActivity(),R.layout.claims,R.id.textView1,m_listItems);
listV = (ListView) claims.findViewById(R.id.listView1);
listV.setOnItemClickListener(new
AdapterView.OnItemClickListener() { // when list is pressed, intent to B
public void onItemClick(AdapterView<?> listView, View view, int position, long id) {
mClickedPosition = position;
if (name.equals("Project")) {
Intent intent = new Intent(Claims1.this.getActivity(), B.class);
intent.putExtra("bitmap", true);
intent.putExtra("name", name);
intent.putExtra("result", result);
startActivityForResult(intent, 0);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) { // receive from B
case 0:
result = data.getStringExtra("text");
name = data.getStringExtra("a");
description = data.getStringExtra("c");
as = Long.parseLong(result);
Log.d("FIRST", "result:" + result);
Text = " " + name + " " + "RM" + result + "";
// m_listItems.clear();
if (mClickedPosition == -1) {
m_listItems.add(Text);
} else {
m_listItems.set(mClickedPosition, Text);
}
adapter.notifyDataSetChanged();
listV.setAdapter(adapter);
break;
}
活动B
if(getIntent().getExtras()!=null) { //if has value pass from A
final String Amount = getIntent().getExtras().getString("result");
final String description1 = getIntent().getExtras().getString("description");
txt1.setText(description1);
txt.setText(Amount);
}
b.setOnClickListener(new View.OnClickListener() { // return to A
public void onClick(View arg0) {
Intent returnIntent = new Intent();
a = "Project";
text = txt.getText().toString(); // amount
returnIntent.putExtra("text", text);
returnIntent.putExtra("a", a);
returnIntent.putExtra("c", c); // receive from Activity C
setResult(Activity.RESULT_OK, returnIntent);
finish();
}
});
viewImage.setImageBitmap(Global.img); // receive from C
}
答案 0 :(得分:2)
使用ArrayList
提取ListView
位置的字符串,如..
listV.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> listView, View view, int position, long id) {
mClickedPosition = position;
String result = m_listItems.get(position); //add this
result = result.substring(2);
if (name.equals("Project")) {
Intent intent = new Intent(Claims1.this.getActivity(), B.class);
intent.putExtra("result", result); // your intent stuff
}
}
});
