ContextAdapterclass is as follows:
ContextAdapter类如下：
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.CheckBox;
import android.widget.TextView;
public class CustomAdapter extends ArrayAdapter<ListData>{
ListData[] items = null;
Context context;
public CustomAdapter(Context context, ListData[] resource) {
super(context, R.layout.activity_list_row, resource);
// TODO Auto-generated constructor stub
this.context = context;
this.items = resource;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflator = ((Activity) context).getLayoutInflater();
convertView = inflator.inflate(R.layout.activity_list_row, parent, false);
TextView name = (TextView) convertView.findViewById(R.id.NameTV);
TextView rollNo = (TextView) convertView.findViewById(R.id.RollNoTV);
CheckBox cb = (CheckBox) convertView.findViewById(R.id.studentCB);
name.setText(items[position].getName());
rollNo.setText(items[position].getRollNo());
if(items[position].getValue() == 1)
cb.setChecked(true);
else
cb.setChecked(false);
return convertView;
}
}
My ListDataclass:
我的ListData班级：
package com.project.attendancemanager;
public class ListData {
String name;
int value, rollno;
ListData(String name, int rollno, int value){
this.name = name;
this.rollno = rollno;
this.value = value;
}
public String getName(){
return this.name;
}
public int getRollNo(){
return this.rollno;
}
public int getValue(){
return this.value;
}
}
Inside the onCreatefunction in the Activity I am doing this:
在onCreateActivity的函数内，我正在这样做：
Listview lv;
ListData[] items;
CustomAdapter adapter = new CustomAdapter(this, items);
lv.setAdapter(adapter);
It would be of great help is someone could point out the mistake in my code. Thanks! Cheers!
有人可以指出我的代码中的错误，这将有很大帮助。谢谢！干杯!

Instead of
代替
rollNo.setText(items[position].getRollNo());
you should use
你应该使用
rollNo.setText(Integer.toString(items[position].getRollNo()));
If you try to set integer as text, you call method setText(int resID) and application try to set as text some string resource with this resID.
如果您尝试将整数设置为文本，则调用方法 setText(int resID) 并且应用程序尝试将一些具有此 resID 的字符串资源设置为文本。
回答by Ismael ozil
SetText doesnt allow integer values
SetText 不允许整数值
Just Add ""+for your code to look like this ""+rollNo.setText(items[position].getRollNo());
只需""+为您的代码添加如下所示""+rollNo.setText(items[position].getRollNo());
this error occurs because setText does not take Integers, it takes Strings
发生此错误是因为 setText 不采用整数，而是采用字符串
回答by Muhammad Ali
You can also use
你也可以使用
String.ValueOf()
in your code to avoid the Resource Not Found Exception .
在您的代码中避免 Resource Not Found Exception 。
Your code will look like this
您的代码将如下所示
rollNo.setText(String.ValueOf(items[position].getRollNo()));
It will work perfectly fine because the SetText() only requires stringsas values to be passed on.
它将工作得很好，因为 SetText() 只需要字符串作为要传递的值。

This might help as well,
这也可能有帮助，
write like this -> textView.setText(""+cartModels.size());
像这样写-> textView.setText(""+cartModels.size());
instead of -> textView.setText(cartModels.size());
而不是 -> textView.setText(cartModels.size());
TextView cartText = view.findViewById(R.id.cartTextDemo);
CartViewModel cartViewModel = ViewModelProviders.of(this).get(CartViewModel.class);
cartViewModel.getmAllCartsVM().observe(this, new Observer<List<CartModel>>() {
@Override
public void onChanged(@Nullable List<CartModel> cartModels) {
if (cartModels != null) {
//cartText.setText(cartModels.size()); // This will not work beacuse it is getting resource instead of string
cartText.setText(""+cartModels.size()); // this will give string
Log.d(TAG, "onChanged: onChanged Called: CartModels Count: "+cartModels.size());
}
}
});
