在itemListner上使用显式意图时java应用程序崩溃

Question

我有一个ListView并适应了ArrayAdatper，我想在单击任何项目时打开新活动，所以我使用了setOnItemClickListener，然后使用了Intent

    ...
    ListView mList = (ListView) findViewById(R.id.list);
    mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            Intent intent = new Intent(MainActivity.this,containerAll.class);
            startActivity(intent);
        }
    });

插入containerAll.class：我有两个片段类：

      public class containerAll extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.view_pager);

    ViewPager mPager = (ViewPager) findViewById(R.id.pager);

    fragmentAdapter adapt = new fragmentAdapter(getSupportFragmentManager());

    mPager.setAdapter(adapt);

   }
}

当我单独运行每个类时，它会工作，但当我运行应用程序时，当我按下listView上的某个项目时，它会崩溃

那么有人知道为什么会发生这种情况吗？ 这是自定义适配器类的名称：

   public class cAdapter extends ArrayAdapter<arrayObject> {

    public cAdapter(Activity context, ArrayList<arrayObject> object){
        super(context,0,object);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        //Create object from layout
         if(convertView == null){
             convertView = LayoutInflater.from(getContext()).inflate(R.layout.inside,parent,false);
         }
         arrayObject item= getItem(position);

        TextView distance = (TextView) convertView.findViewById(R.id.distance);
        // Change image inside the ifnlator
        ImageView image = (ImageView) convertView.findViewById(R.id.pic);
        image.setImageResource(item.imageRes);

        TextView name = (TextView) convertView.findViewById(R.id.name);
        name.setText(item.mName);

        distance.setVisibility(View.GONE);
        if(item.distance != null) {

            distance.setText(item.distance);
            distance.setVisibility(View.VISIBLE);
        }

        return convertView;
    }

  }

这是logCat：

Answer 1

错误本身就说明了一切。将您的活动添加到清单中，错误就会消失。 像这样

<activity android:name="YourActivityName" >
</activity>

希望这有帮助。：）
