android - Android 中 ArrayAdapter 中的 CheckBox 和 TextView

Question

我在 android 中的 ListView 的每一行都有复选框和 TextView 。如果我点击复选框，我会设置我的复选框被选中，但是如果我点击 TextView，我如何设置我的复选框被选中。这是我的代码示例。谢谢你的时间。

public class PitanjaAdapter extends ArrayAdapter<Odgovor>{

private ArrayList<Odgovor> odgovorList;
Context context;
private Typeface custom_font;

public PitanjaAdapter(Context context, int textViewResourceId, ArrayList<Odgovor> odgovorList) {
    super(context, textViewResourceId, odgovorList);
    this.context = context;
    this.odgovorList = new ArrayList<Odgovor>();
    this.odgovorList.addAll(odgovorList);
    this.custom_font = Typeface.createFromAsset(context.getAssets(), "fonts/Aller.ttf");
}

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

    ViewHolder holder = null;
    if (convertView == null){
        LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = vi.inflate(R.layout.pitanja_entry, null);

        holder = new ViewHolder();
        holder.code = (TextView) convertView.findViewById(R.id.code);
        holder.code.setTypeface(custom_font);
        holder.name = (CheckBox) convertView.findViewById(R.id.checkBox1);
        convertView.setTag(holder);

        holder.name.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {

                CheckBox cb = (CheckBox) v;
                Odgovor country = (Odgovor) cb.getTag();
                country.setSelected(cb.isChecked());

            }



        });
        holder.code.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {


            }
        });

    }
    else {
        holder = (ViewHolder) convertView.getTag();
    }
    Odgovor country = odgovorList.get(position);
    holder.code.setText(country.getContents());
    holder.name.setChecked(country.isSelected());
    holder.name.setTag(country);
    if (odgovorList.get(position).getGreen() != 0 && odgovorList.get(position).getRed() != 0){
        if (country.isSelected() && Integer.parseInt(country.getIs_correct()) == 1){
            holder.code.setBackgroundResource(R.drawable.tocan_odgovor_drawable);
            holder.name.setBackgroundResource(R.drawable.ikona_box2_tocno);
        } else if (country.isSelected() && Integer.parseInt(country.getIs_correct()) == 0){
            holder.code.setBackgroundResource(R.drawable.netocan_odgovor_drawable);
            holder.name.setBackgroundResource(R.drawable.ikona_box2_netocno);
        } else if (!country.isSelected() && Integer.parseInt(country.getIs_correct()) == 0){
            holder.code.setBackgroundResource(R.drawable.netocan_odgovor_drawable);
            holder.name.setBackgroundResource(R.drawable.selector_check);
            holder.name.setEnabled(false);
        } else if (!country.isSelected() && Integer.parseInt(country.getIs_correct()) == 1){
            holder.code.setBackgroundResource(R.drawable.tocan_odgovor_drawable);
            holder.name.setBackgroundResource(R.drawable.selector_check);
            holder.name.setEnabled(false);
        }
    }


    return convertView;
}

public void colorized(Odgovor odgovor){
    odgovor.setRed(Color.RED);
    odgovor.setGreen(Color.WHITE);
}

private class ViewHolder{

    public TextView code;
    public CheckBox name;


}

我把它放在这里是因为我不能评论:(。你试过吗

checkbox.setChecked(myboolean)

编辑

你应该把它放出来

public class PitanjaAdapter extends ArrayAdapter<Odgovor>{
public ViewHolder holder;

然后

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

if (convertView == null){
    LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    convertView = vi.inflate(R.layout.pitanja_entry, null);

    holder = new ViewHolder();
    holder.code = (TextView) convertView.findViewById(R.id.code);
    holder.code.setTypeface(custom_font);
    holder.name = (CheckBox) convertView.findViewById(R.id.checkBox1);
    convertView.setTag(holder);

    holder.name.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View v) {

            CheckBox cb = (CheckBox) v;
            Odgovor country = (Odgovor) cb.getTag();
            country.setSelected(cb.isChecked());

        }

通过这种方式，您可以在 getView 中给它一个值，但您可以从 onClick 访问它，因为它是一个外部值。但是在使用它之前一定要确保在某个地方给它一个值，否则它将为 null

要将 textview 用作按钮，您必须使用 onclicklistener

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView text= (TextView) findViewById(R.id.textView);
    text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            CheckBox A = (CheckBox) findViewById(R.id.checkBox2);
            A.setChecked(!A.isChecked());
        }
    });
}
