我有一个列表视图,其中显示联系人姓名。有更多的值与列表视图相关联。当我在列表视图中按下行时,我将Hashmap发送给其他活动,并基于HashMap大小,我想动态创建TextView并为那些动态创建的文本视图(如Name,Email,PhoneNo)分配值。创建多个Textviews并为其动态分配值
listview.OnItemClickListner
mListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id) {
// TODO Auto-generated method stub
@SuppressWarnings("unchecked")
HashMap<String, String> o = (HashMap<String, String>) mListView.getItemAtPosition(position);
Intent i = new Intent (Contacts.this , Contacts_Detail.class);
i.putExtra("HASHMAP", o);
startActivity(i);
}
});
联系人详细信息类
public class Contacts_Detail extends Activity {
LinearLayout mLinearlayout;
TextView rowTextView;
HashMap<String, String> ModuleName;
ArrayList<String> KEY;
List<TextView> allTxts;
private LayoutInflater inflater;
View layout;
@SuppressWarnings("unchecked")
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
mLinearlayout = (LinearLayout) findViewById(R.id.LinearLayout);
Bundle extras = getIntent().getExtras();
if (extras != null)
{
//map = HashMap<String, String>>getIntent().getSerializableExtra("MODULE_LIST");
ModuleName = (HashMap<String, String>) extras.getSerializable("HASHMAP");
//KEY = (ArrayList<String>) extras.getSerializable("KEY");
}
else
{
Toast.makeText(getApplicationContext(), "No Data Found", Toast.LENGTH_LONG).show();
return;
}
int N = ModuleName.size(); // total number of textviews to add
final TextView[] myTextViews = new TextView[N]; // create an empty array;
allTxts = new ArrayList<TextView>();
for (int i = 0; i < N; i++) {
// create a new textview
rowTextView = new TextView(this);
allTxts.add(rowTextView);
// set some properties of rowTextView or something
rowTextView.setText("This is TextView #" + i);
rowTextView.setId(i);
// add the textview to the linearlayout
mLinearlayout.addView(rowTextView);
// save a reference to the textview for later
myTextViews[i] = rowTextView;
}
}}
正如你看到的所有textviews创建succesfully.But我想HASHMAP值分配给所有的动态创建文字浏览。 如何做到这一点。?
我可以使用布局充气器的概念。 ?
在此先感谢
为什么不创建一个单一的TextView和使用追加或使用一个ListView – Raghunandan
@Raghunandan我有很多工作要做,这些Textviews后,将数据添加到它。不能使用listview。 –
@BhanuSharma没有让你指出。 –
