从Android中单击ListView项目启动活动

标签： android android-listview

我有一个带图片的自定义列表视图。当我按下（点击）列表视图时，需要打开个人活动。但是当我按下文本视图时，它会显示错误消息（崩溃应用程序）。这是我的代码。在这方面你能帮我吗？

SMSMainPage.java：

public class SmsMainPage extends AppCompatActivity {

    //log tag
    private static final String TAG = "SaidursApp";

    // Array of strings...
    String[] mobileArray = {"Android","IPhone","WindowsMobile","Blackberry"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.v(TAG, "SmsMainPage  onCreate function started");
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_sms_main_page);

        //Code for showing image and list view item
        ListView listView = (ListView) findViewById(R.id.mobile_list);
        listView.setAdapter(new MobileArrayAdapter(this, mobileArray));


        Log.v(TAG, "SmsMainPage  setOnItemClickListener started");
        try {
            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    final TextView mTextView = (TextView) view;
                    switch (position) {
                        case 0:
                            Intent newActivity0 = new Intent(SmsMainPage.this, android.class);
                            startActivity(newActivity0);
                            break;
                        default:
                            // Nothing do!
                    }
                }
            });
        }catch (Exception e){
            e.printStackTrace();
        }
    }

MobileArrayAdapterCode.java：

public class MobileArrayAdapter extends ArrayAdapter<String> {

    //log tag
    private static final String TAG = "SaidursApp";

    private final Context context;
    private final String[] values;

    public MobileArrayAdapter(Context context, String[] values) {
        super(context, R.layout.activity_listview, values);
        Log.v(TAG, "MobileArrayAdapter  function started");
        this.context = context;
        this.values = values;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        Log.v(TAG, "MobileArrayAdapter getView  function started");
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View rowView = inflater.inflate(R.layout.activity_listview, parent, false);
        TextView textView = (TextView) rowView.findViewById(R.id.label);
        ImageView imageView = (ImageView) rowView.findViewById(R.id.logo);
        textView.setText(values[position]);

        // Change icon based on name
        String s = values[position];

        System.out.println(s);

        if (s.equals("WindowsMobile")) {
            imageView.setImageResource(R.drawable.windowsmobile_logo);
        } else if (s.equals("IPhone")) {
            imageView.setImageResource(R.drawable.ios_logo);
        } else if (s.equals("Blackberry")) {
            imageView.setImageResource(R.drawable.blackberry_logo);
        } else {
            imageView.setImageResource(R.drawable.android_logo);
        }

        return rowView;
    }
}
