problema listview con adapter custom

ciao
chiedo scusa , non riesco a risolvere l'errore seguente :

ho definito gli xml seguenti :

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

<Button
android:id="@+id/ritorna"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:text="torna" />

<listView android:id="@+id/listimages"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</listView>

</LinearLayout>

listimages_riga.xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listimages_riga"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
androidrientation="horizontal" >

<CheckBox
android:id="@+id/checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/listimages_riga_image"
android:layout_marginLeft="14dp"
android:layout_weight="0.15" />

<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/checkBox"
android:layout_alignBottom="@+id/checkBox"
android:layout_marginLeft="19dp"
android:layout_toRightOf="@+id/checkBox"
android:text="TextView" />

<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/foto1" />

</RelativeLayout>


il 2° xml descrive la riga del 1° xml , i 2 xml sono gestiti dall'activity ListImagesAct ;

l'activity seguente listaVociAct visualizza una listview e , selezionando una delle sue righe , dovrebbe chiamare l'activity ListImagesAct che prepara il 1° xml secondo il tracciato del 2° xml :


import java.util.ArrayList;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;

public class listaVociAct extends Activity {

protected Context mContext;
protected ArrayList<String> mat1;
private ListView listav ;
private ArrayAdapter<String> listAdapt ;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listavoci);
mContext = this;

Intent int2 = getIntent();
mat1 = int2.getStringArrayListExtra("matrice1");

// Find the ListView , lista delle voci selezionabili
listav = (ListView) findViewById( R.id.listavoci );


// Collegamento con la sorgente dati da visualizzare.
listAdapt = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mat1);

// Set the ArrayAdapter as the ListView's adapter.
listav.setAdapter( listAdapt );

//controlla elemento della lista selezionato
listav.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
selectActivity(position);
}

// Metodo selezione , per semplicita faccio tutto uguale
private void selectActivity(int position) {
switch (position) {
case 0:
Intent myIntent1 = new Intent(listaVociAct.this,ListImagesAct.class);
myIntent1.putStringArrayListExtra("matrice1", mat1);
listaVociAct.this.startActivity(myIntent1);
break;
case 1:
Intent myIntent2 = new Intent(listaVociAct.this,ListImagesAct.class);
myIntent2.putStringArrayListExtra("matrice1", mat1);
listaVociAct.this.startActivity(myIntent2);
break;
case 2:
. . . . . .
}
});

}

l'activity ListImagesAct è così fatta :

package com.example.pippo;

import java.util.ArrayList;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Gallery;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;

public class ListImagesAct extends Activity {

protected Context mContext;
protected ArrayList<String> mat1;
private ListView listav ;
private myAdapter mioAdapt ;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listimages);
mContext = this;

Intent int2 = getIntent();
mat1 = int2.getStringArrayListExtra("matrice1");

// Find the resource : listView del 1° xml
listav = (ListView) findViewById( R.id.listimages );

// Collegamento con la sorgente dati da visualizzare , uso un adapter mio
mioAdapt = new myAdapter(this, mat1);

// Set the adapter.
listav.setAdapter( mioAdapt );

//controllo elemento della lista selezionato
listav.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
selectActivity(position);
}

// Metodo selezione , per semplicità torno indietro
private void selectActivity(int position) {
switch (position) {
case 0:
Intent myIntent1 = new Intent(ListImagesAct.this,listaVociAct.class);
myIntent1.putStringArrayListExtra("matrice1", mat1);
ListImagesAct.this.startActivity(myIntent1);
break;
case 1:
. . . . .
}
}
});

}

}


mioAdapter è fatto così :

package com.example.pippo;

import java.util.ArrayList;

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.ImageView;
import android.widget.TextView;

public class myAdapter extends ArrayAdapter<String> {
private final Context context;
private final ArrayList<String> values;

// Keep all Images in array
public Integer[] mThumbIds = {
R.drawable.foto1, R.drawable.foto2,
R.drawable.foto3, R.drawable.foto4,
R.drawable.foto5, R.drawable.foto6,
R.drawable.foto7, R.drawable.foto8,
R.drawable.foto9
};

public myAdapter(Context context, ArrayList<String> values) {
super(context, R.layout.listimages_riga, values);
this.context = context;
this.values = values;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.listimages_riga, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.textView);
ImageView imageView = (ImageView) rowView.findViewById(R.id.imageView1);
CheckBox checkBox = (CheckBox) rowView.findViewById(R.id.checkBox);

textView.setText(values.get(position));
imageView.setImageResource(mThumbIds[position]);

return rowView;
}
}


,'esecuzione mi da il seguente errore , ho provato a fare il debug ma non ho ricavato niente ,
forse perchè sono poco esperto :

Ciao,
nell'XML penso che <listView> sia sbagliato ... prova a scriverlo cosi <ListView> ... se non va, posta anche l'AndroidManifest.xml !

 

grazie
hai ragione ho fatto come dicevi tu ed è funzionato ;
una domanda : ho notato che l'ultima riga del ListView ha solo l'immagine , che occupa tutto lo spazio ,
ho dovuto impostare l'immagine così :


<ImageView
android:id="@+id/imageView1"
android:layout_width="40dp"
android:layout_height="40dp"
android:scaleType="fitXY"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/foto1" />

sai dirmi perchè succede (e solo per lultima riga) ?

grazie mille
ciao

 

Riesci a mettere una print screen per capire l'effetto sbagliato che ti crea ?
Al 90% il problema sarà sulla gravità dei vari componenti del layout ... o sul settaggio delle proprietà width e height (per una equa distribuzione dei componenti nel layout mi aspetto un FILL_PARENT).
Magari prova a darti una lettura qui : ViewGroup.LayoutParams | Android Developers
Se non ne esci ... metti una print screen
Per le prossime volte inserisci il codice tramite tag CODE in modo da renderlo più leggibile !
