我有两个编辑框。输入的值必须放在自定义列表视图中,它的工作正常......
但我想将这些值永久保存在列表视图中。这样,如果手机关闭并再次运行应用程序,则必须保存这些值..就像必须保存电话联系号码和姓名..这里附上代码
public class Editcard extends Activity{
EditText cardname,cardDescription ;
MyApplication app;
@SuppressWarnings({ "unchecked", "rawtypes" })
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.editcredit);
app = ((MyApplication) getApplicationContext());
cardname =(EditText)findViewById(R.id.cardash);
cardDescription =(EditText)findViewById(R.id.editdescription);
Button save =(Button)findViewById(R.id.save);
save.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
app.carddata =cardname.getText().toString();
System.out.println("Gotcardname"+app.carddata);
app.descriptiondata =cardDescription.getText().toString();
System.out.println("gotDescription"+app.descriptiondata);
app.arryList.add(app.carddata);
app.arryList1.add(app.descriptiondata);
Intent saveIntent =new Intent(Editcard.this,Newcard.class);
startActivity(saveIntent);
}
});
}
}
public class MyApplication extends Application{
ArrayList<String> arryList = new ArrayList<String>();
ArrayList<String> arryList1 = new ArrayList<String>();
String carddata,descriptiondata,=null;
}
public class Newcard extends Activity {
MyAdapter adapter;
ListView listView;
LayoutInflater lay;
MyApplication app;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.newcard);
app = ((MyApplication) getApplicationContext());
TextView newcard =(TextView)findViewById(R.id.newcard);
newcard.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent card = new Intent(Newcard.this,Editcreditcard.class);
startActivity(card);
}
});
listView = (ListView) findViewById(R.id.cardlist);
adapter =new MyAdapter(this, app.arryList,app.arryList1);
listView.setAdapter(adapter);
}
public class MyAdapter extends BaseAdapter {
Context context = null;
ArrayList<String> items= null;
ArrayList<String> items1= null;
public MyAdapter(Newcard newcard, ArrayList<String> items,
ArrayList<String> items1) {
// TODO Auto-generated constructor stub
this.items = items;
this.items1 = items1;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return items.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return items;
//return items.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View layout = null;
TextView produ = null;
TextView desc = null;
if (convertView == null) {
lay = LayoutInflater.from(getApplicationContext());
layout = lay.inflate(R.layout.customlist, null);
} else {
layout = convertView;
}
produ = (TextView) layout.findViewById(R.id.card);
produ.setText("" +app.arryList.get(position));
desc= (TextView) layout.findViewById(R.id.descrip);
desc.setText("" +app.arryList1.get(position));
return layout;
}
}
}
