Custom ListView Doesn't work
Question
I just wrote this code and it works like this: it gets a number and a string + an image and put them into Array Lists and then put them into ListView, but some how it doesn't work and i could't find the problem
MainActivity
package com.arashsm79.asm.mathcity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
public ListView list;
public ArrayList<Integer> id = new ArrayList<>();;
public ArrayList<String> names = new ArrayList<>();;
public ArrayList<Bitmap> images = new ArrayList<>();;
private static final int CAMERA_REQUEST = 1888;
public static Bitmap ph;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// <View>
list = (ListView) findViewById(R.id.listView);
final TextView id_tv = (TextView) findViewById(R.id.id_tv);
final TextView names_tv = (TextView) findViewById(R.id.name_id);
Button done = (Button) findViewById(R.id.done_btn_id);
Button cancel = (Button) findViewById(R.id.done_btn_id);
Button img = (Button) findViewById(R.id.img);
// </Views>
done.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(id_tv.getText() != null && names_tv.getText() != null && ph != null) {
id.add(Integer.parseInt(String.valueOf(id_tv.getText())));
names.add(String.valueOf(names_tv.getText()));
images.add(ph);
}else Toast.makeText(getApplicationContext(), "از پر کردن جاهای خالی و قرار دادن عکس اطمینان حاصل فرمایید", Toast.LENGTH_SHORT).show();
id_tv.setText("");
names_tv.setText("");
ph = null;
}
});
img.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
ListConfig adapter = new ListConfig(MainActivity.this, id, names, images);
list.setAdapter(adapter);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ph = photo;
}
}
}
And this is the xml for MainActivity
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.arashsm79.asm.mathcity.MainActivity"
android:background="#cff9cd">
<ListView
android:layout_width="match_parent"
android:layout_height="400dp"
android:id="@+id/listView"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
<Button
android:layout_width="80dp"
android:layout_height="40dp"
android:text="Done"
android:id="@+id/done_btn_id"
android:background="@drawable/buttons"
android:layout_below="@+id/listView"
android:layout_alignParentEnd="true"
android:layout_marginTop="-5dp"
android:textStyle="bold" />
<Button
android:layout_width="100dp"
android:layout_height="40dp"
android:text="Cancel"
android:id="@+id/cancel_btn_id"
android:layout_alignStart="@+id/done_btn_id"
android:background="@drawable/cancel"
android:layout_marginTop="440dp"
android:textStyle="bold" />
<EditText
android:layout_width="50dp"
android:layout_height="50dp"
android:inputType="number"
android:ems="10"
android:id="@+id/id_tv"
android:layout_below="@+id/listView"
android:layout_toStartOf="@+id/done_btn_id"
android:layout_marginTop="13dp"
android:layout_marginRight="5dp"
android:background="@android:drawable/checkbox_off_background"
android:hint="ID"
android:paddingLeft="15dp"
android:textStyle="bold" />
<EditText
android:layout_width="170dp"
android:layout_height="wrap_content"
android:inputType="textMultiLine"
android:ems="10"
android:id="@+id/name_id"
android:layout_below="@+id/listView"
android:layout_toStartOf="@+id/id_tv"
android:layout_alignBottom="@+id/id_tv"
android:textStyle="bold" />
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="40dp"
android:layout_height="70dp"
android:text="img"
android:id="@+id/img"
android:layout_below="@+id/listView"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true"
android:background="@drawable/img"
android:textStyle="bold" />
</RelativeLayout>
And here is my Adapter class
package com.arashsm79.asm.mathcity;
import android.app.Activity;
import android.graphics.Bitmap;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
public class ListConfig extends ArrayAdapter<Bitmap> {
public ArrayList<Integer> id_config = new ArrayList<>();;
public ArrayList<String> names_config = new ArrayList<>();;
public ArrayList<Bitmap> images_config = new ArrayList<>();;
public Activity context_config;
public ListConfig(Activity context, ArrayList<Integer> id, ArrayList<String> names, ArrayList<Bitmap> images) {
super(context,R.layout.list, images);
context_config = context;
id_config = id;
names_config = names;
images_config = images;
}
public View getView(int position, View view, ViewGroup parent){
LayoutInflater inf = context_config.getLayoutInflater();
View row = inf.inflate(R.layout.list, null, true);
TextView name = (TextView) row.findViewById(R.id.tozihat);
TextView id = (TextView) row.findViewById(R.id.shomare);
ImageView image = (ImageView) row.findViewById(R.id.aks);
name.setText(names_config.get(position));
id.setText(id_config.get(position));
image.setImageBitmap(images_config.get(position));;
return row;
}
}
And the last one is my xml for every row in list
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<ImageButton
android:layout_width="100dp"
android:layout_height="100dp"
android:id="@+id/aks"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="220dp"
android:layout_height="100dp"
android:id="@+id/tozihat"
android:layout_alignParentTop="true"
android:layout_toEndOf="@+id/aks"
android:textAlignment="viewEnd"
android:padding="5dp"
android:textStyle="bold"
android:textSize="20dp"
android:hint="توضیحات" />
<TextView
android:layout_width="60dp"
android:layout_height="60dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="@+id/shomare"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_marginTop="27dp"
android:paddingLeft="0dp"
android:paddingTop="15dp"
android:textAlignment="center"
android:hint="شماره" />
</RelativeLayout>

I saw your code this line:
id.add(Integer.parseInt(String.valueOf(id_tv.getText())));
This means you get the String and parse it into a Integer, as you did I think the String value is meaningful, so it must not be a String resource ID. This is the reason.
So, the easiest way to fix this is to replace you code (in your Adapter.getView() ):
id.setText(id_config.get(position));
with
id.setText(""+id_config.get(position));

replace the line :
id.setText(id_config.get(position));
with :
id.setText(String.valueOf(id_config.get(position)));
