android - 无法解析方法 'super(android.content.context,int,int,java.util.arraylist)'

Question

这是我的自定义列表适配器

private class MyAdapter extends ArrayAdapter<ArrayList<BluetoothDevice>> {

    ArrayList<BluetoothDevice> data;
    Context context;

    public MyAdapter(Context context, int resource, int textViewResourceId, ArrayList<BluetoothDevice> objects) {
        super(context, resource, textViewResourceId,objects);
        this.context=context;
        this.data=objects;
    }

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

        View v=getLayoutInflater().inflate(R.layout.row,parent,false);

        TextView textView=(TextView)findViewById(R.id.row_textview);

        BluetoothDevice device=data.get(position);

        textView.setText(device.getName()+"");



        return v;
    }
}

我正在传递一个蓝牙设备的数组列表，构造函数导致了问题

Canot resolve method 'super(android.content.context,int,int,java.util.arraylist<android.Bluetooth.Bluetoothdevices>)'

我在这里设置适配器

listView.setAdapter(new MyAdapter(getApplicationContext(),R.layout.row,R.id.row_textview,bluetoothDeviceArrayList));

请帮忙!

尝试改变这个

  private class MyAdapter extends ArrayAdapter<ArrayList<BluetoothDevice>> {

对此

  private class MyAdapter extends ArrayAdapter<BluetoothDevice> {

删除 ArrayList 部分。这只需要一个元素将处理的数据类型。
