Bundle sorunum, bakarmısınız?
Merhaba, burada yeniyim. Yaklaşık 1 aydır android projem üzerinde çalışıyorum. Her şeyi hazır ama işlevlerde sorun çıkıyor.
Sorun tam olarak şu; Bir sayfada textview'ler var. Bu textview'leri string'e atadım. Sayfadaki tuşa basarak listview'e gidiyor. Maddelerin her birinde bundle var, bundle'lar önceki sayfadaki textview'in yazısına farklı bir string ataması gerekiyor. Ama program tam burada budle'ları iletirken hata veriyor ve durduruluyor.
En başta anlattığım sayfanın kodu;
package com.monsterdroid.howtoloseweight;

import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

import android.widget.TextView;
public class ekranbir extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ekran1);Button button1=(Button) findViewById(R.id.button1);
Button button2=(Button) findViewById(R.id.button);
final TextView baslik = (TextView) findViewById(R.id.baslik);

final TextView icerik = (TextView) findViewById(R.id.icerik);
Bundle veribaslik = getIntent().getExtras();
String baslikveri = veribaslik.getString("baslikveri");
baslik.setText(baslikveri);
Bundle verimadde = getIntent().getExtras();
String maddeveri = verimadde.getString("maddeveri");
madde.setText(maddeveri);
Bundle veriicerik = getIntent().getExtras();
String icerikveri = veriicerik.getString("icerikveri");
icerik.setText(icerikveri);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent("com.monsterdroid.howtoloseweight.ANASAYFA"));
}
});
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent("com.monsterdroid.howtoloseweight.MAINACTIVITY"));
}
});
}public boolean onCreateOptionsMenu (Menu menu){
super.onCreateOptionsMenu(menu);
MenuInflater menutanim = getMenuInflater();
menutanim.inflate(R.menu.menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()){
case R.id.home:

Bu da listview sayfasının kodu;
