خارج شدن از برنامه هنگام کار با listView

[CRbreeze]

سلام دوستان من کد زیر رو وقتی اجرا میکنم بعد از کلیک روی دکمه از برنامه خارج میشه ... کسی اگه میدونه مشکل کار کجاست راهنمایی کنه لطفا ...


کلاس main:



public class MainActivity extends ActionBarActivity {




@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MainActivity.this.startActivity(new Intent(MainActivity.this,List.class));
}
});


}


کلاس list:



public class List extends ListActivity {


private String[] array = {"one","tow","three","four"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tow);
setListAdapter (new ArrayAdapter <String> (this, android.R.layout.simple_list_item_1,
array));
}


}

سلام
اکتیویتی هارو توی manifest معرفی کردی...؟؟

[CRbreeze]

آره ... یادم شده بود تعریف کنم ..... ولی بعد از تعریف باز هم از برنامه خارج میشه ....

[msroid]

اون لیست ویو توی لایوت tow باید آیدیش list باشه. اینم چک کن.

[CRbreeze]

متاسفانه این قسمت هم همینطوره که میگید:

<ListView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/list"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />

[msroid]

توی خطاهایی که گذاشتی یه جایی داره NullPointerException میده.
کد مربوط به دوتا اکتیویتی که تو manifest هست رو بذار.
یه بارم اون ActionBarActivity رو تغییر بده به Activity و اجرا کن ببین تغییری میکنه یا نه.
الانم همون خطاهای قبلی رو میده یا عوض شدن...؟؟

android:layout_height="wrap_content"
android:id="@+id/list"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
اونجوری نه، اینجوری :

android:id="@android:id/list"

[CRbreeze]

این خطا رو میده RelativeLayout cannot be cast to android

[msroid]

اون id رو درست کن که دوستمون اشاره کردن. android رو جا انداختی

[CRbreeze]

اونجوری نه، اینجوری :

android:id="@android:id/list"



ممنون دوست عزیز درست شد

این خطای NullPointerException معمولا چه موقعی پیش میاد؟ آخه من یه برنامه دیگه دارم متاسفانه یه قسمت از ارور مربوط به لیست ویو بود قسمت دیگه کار با دیتا بیس هست که این خطا رو داره

[msroid]

ممنون دوست عزیز درست شد

زمانی که به چیزی ارجاع داده میشه که وجود نداره و یا تعریف و مقدار دهی نشده باشه.
برای مثال الان شما داشتی از یک لیست ویو استفاده میکردی که وجود نداشت. چون کلمه android رو جا انداخته بودی اون لیست ویو دیگه اونی نبود که اندروید میشناخت و در واقع نمیتونست اون لیست ویو مدنظر رو پیدا کنه برای همینم این خطا رو میداد

ممنون دوست عزیز ... خیلی متشکرم که وقت گذاشتید...
