Question

我在android中的listview的每一行都有复选框和textview。如果我单击复选框，我会设置我的复选框，但如果单击TextView，如何设置复选框。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;


}

}

我把它放在这里因为我无法评论:(。 Hace你试过

checkbox.setChecked(myboolean)

修改

你应该把它拿出来

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()); }

这样你在getView中给它一个值，但你可以从onClick访问它，因为它是一个外部值。但是在使用它之前总是确保给它一个值，否则它将为null

要将textview用作buttom，你必须使用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()); } }); }

Android中的ArrayAdapter中的CheckBox和TextView
