我正在我的应用程序中动态添加一个复选框,并且我想删除已检查的记录。但是,我没有得到复选框的 ID。我怎样才能做到这一点?
代码:
package com.my.StudentInfoManagement;
public class ListData extends Activity{
DataHelper dh;
TableLayout tb;
CheckBox[] ch=new CheckBox[50];
EditText ed;
int a[]=new int[50];
int k=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.listdataxml);
dh=new DataHelper(this);
System.out.println("in list data");
List<String> names= this.dh.selectAll();
ed=(EditText) findViewById(R.id.ed_id);
tb=(TableLayout) findViewById(R.id.table);
int i,j=1;
TextView name1 = null,id,dob,gender,branch,email,address,mobile;
String name11,id1 = null,dob1,gender1,branch1,email1,address1,mobile1;
TableRow tr=new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
TextView tv=new TextView(this);
String c = null;
String data[]=new String[50];
int cnt=0;
for(String name:names)
{
if((!name.equals("-999")))
{
data[cnt]=name;
cnt++;
System.out.println("........."+name);
}
else
{
cnt=0;
name1=new TextView(this);
name1.setText(data[1]+" ");
id=new TextView(this);
id.setText(data[0]+" ");
System.out.println("ID is...."+data[0]);
dob=new TextView(this);
dob.setText(data[3]+" ");
gender=new TextView(this);
gender.setText(data[2]+" ");
branch=new TextView(this);
branch.setText(data[4]+" ");
mobile=new TextView(this);
mobile.setText(data[5]+" ");
email=new TextView(this);
email.setText(data[6]+" ");
address=new TextView(this);
address.setText(data[7]+" ");
tr=new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
ch[k]=new CheckBox(this);
System.out.println("sysout");
i=Integer.parseInt(data[0]);
ch[k].setId(i);
tr.addView(ch[k]);
a[k++]=i;
tr.addView(id);
tr.addView(name1);
tr.addView(dob);
tr.addView(gender);
tr.addView(branch);
tr.addView(mobile);
tr.addView(email);
tr.addView(address);
tb.addView(tr,new TableLayout.LayoutParams( LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
j++;
System.out.println("count"+j);
}
}
}
public void delete(View v){
System.out.println("In delete");
int bb=k,id ;
for (int i=0; i <k; i++)
{
final int j = a[i];
System.out.println("in for loop"+j);
ch[j].setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
System.out.println("Checked ID :: " + ch[j].getId());
}
});
}
System.out.println("00000000000000000..."+id);
dh.deleteData(id);
}
}
