java - ListView 崩溃 Activity

Question

这个问题已经有答案了:

android.content.res.Resources$NotFoundException: String resource ID #0x0 (8 个回答)

已关闭 7 年前。

我想将从数据库检索到的一些数据添加到 ListView。

这是列表布局:list.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

    <TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:hint="@string/id"
android:id="@+id/tlist1"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginLeft="10dp"
android:layout_marginStart="0dp"
android:layout_marginTop="32dp"
android:textAlignment="center"/>

    <TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:hint="@string/Sujet"
android:id="@+id/tlist2"
android:layout_alignTop="@+id/tlist1"
android:layout_toRightOf="@+id/tlist1"
android:layout_marginLeft="30dp"
android:layout_marginStart="30dp"
android:textAlignment="center"/>

    <TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceMedium"
android:hint="@string/texte"
android:textAlignment="center"
android:id="@+id/tlist3"
android:layout_alignTop="@+id/tlist2"
android:layout_toRightOf="@+id/tlist2"
android:layout_marginLeft="47dp"
android:layout_marginStart="47dp"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>

收到的包含ListView的布局:received.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
>

    <ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/listtt"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />

</RelativeLayout>

java文件:received.java

package com.example.oussama.setram;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.Toast;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;

/**
 * Created by oussama on 09/03/2016.
 */
public class received extends Activity {
private ArrayList<msg> per=new ArrayList<msg>();
    ListView listee;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.received);
        msg msm = new msg();
        msm.setSujet("aplication mobile");
        msm.setTexte("hadj ben ali");
        msm.setId(1);
per.add(msm);
        MonAdapter adapter = new MonAdapter(getApplicationContext(), R.layout.list, per);
listee = (ListView) findViewById(R.id.listtt);
listee.setAdapter(adapter);
    }




}

适配器:MonAdapter.java

package com.example.oussama.setram;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageButton;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;
/**
 * Created by oussama on 19/04/2016.
 */
public class MonAdapter extends ArrayAdapter<msg> {
      Context context;
int idLayout;
    ArrayList<msg> per;
    LayoutInflater vi;
public MonAdapter(Context context, int idLayout, ArrayList<msg> per) {
super(context,idLayout,per);
this.context=context;
this.idLayout=idLayout;
this.per =per;
    }
@Override
public View getView(int position, View convertView, ViewGroup parent) {
        View v=convertView;
if(v==null){
vi = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
            v=vi.inflate(idLayout,parent,false);
        }
        msg c = per.get(position);


if(c!=null){
            TextView sujet = (TextView) v.findViewById(R.id.tlist2);
            TextView text = (TextView) v.findViewById(R.id.tlist3);
            TextView id = (TextView)v.findViewById(R.id.tlist1);
if(sujet!=null){
                sujet.setText(c.getSujet());}
if(text!=null){
                text.setText(c.getTexte());}
if(id!=null){
                id.setText(c.getId());
            }
        }
return v;
    }
}

插入数据的类:msg.java

package com.example.oussama.setram;

/**
 * Created by oussama on 30/04/2016.
 */
public class msg {

private int id;
private String sujet;
private String texte;
public msg(){
id=1;
sujet="";
texte="";

}
public msg(int id,String sujet,String texte) {
this.id = id;
this.sujet=sujet;
this.texte=texte;
    }

public int getId(){
return id;
    }
public String getSujet(){
return sujet;
}
public String getTexte(){
return texte;
    }

public void setId(int id) {
this.id = id;
    }

public void setTexte(String texte) {
this.texte = texte;
    }

public void setSujet(String sujet) {
this.sujet = sujet;
    }
}

Answer 1

RelativeLayout 没有orientation 参数。并更改

id.setText(c.getId());

至

id.setText(String.valueOf(c.getId()));
