ImageButton出错

Question

我是错误的，不知道如何修复它们

MainActivity

setListAdapter(new ConteudoActivity(ctx, R.layout.suport_activity,
                option_icon, option_text));

ConteudoActivity

ImageButtonib = (ImageButton)convertView.findViewById(R.id.image_adicionar);
ib.setImageDrawable(mButton.getDrawable(position));

活动数组

import android.widget.ImageView;
import android.widget.TextView;

public class ConteudoActivity extends ArrayAdapter < String > {

  private LayoutInflater mInflater;
  private ImageButton mButton;
  private String[] mStrings;
  private TypedArray mIcons;

  private int mViewResourceId;

  public ConteudoActivity(Context ctx, int viewResourceId,
    String[] strings, TypedArray icons, TypedArray ibutton) {
    super(ctx, viewResourceId, strings);

    mInflater = (LayoutInflater) ctx.getSystemService(
      Context.LAYOUT_INFLATER_SERVICE);

    mStrings = strings;
    mIcons = icons;
    mButton = ibutton;
    mViewResourceId = viewResourceId;
  }


  @

    return mStrings.length;
  }

  @

    return mStrings[position];
  }

  @

    return 0;
  }

  @

  public View getView(int position, View convertView, ViewGroup parent) {
    convertView = mInflater.inflate(mViewResourceId, null);


    ImageView iv = (ImageView) convertView.findViewById(R.id.option_icon);
    iv.setImageDrawable(mIcons.getDrawable(position));

    ImageButton ib = (ImageButton) convertView.findViewById(R.id.image_adicionar);
    ib.setImageDrawable(ImageButton.getDrawable(position));


    TextView tv = (TextView) convertView.findViewById(R.id.option_text);
    tv.setText(mStrings[position]);

    return convertView;
  }
}

MainActivity

package com.kolla.projeto;


import android.app.ListActivity;
import android.content.Context;
import android.content.res.Resources;
import android.content.res.TypedArray;
import android.os.Bundle;

public class MainActivity extends ListActivity{
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Context ctx = getApplicationContext();
        Resources res = ctx.getResources();

        String[] option_icon = res.getStringArray(R.array.Logo);
        TypedArray option_text = res.obtainTypedArray(R.array.NomeProd);

        setListAdapter(new ConteudoActivity(ctx, R.layout.suport_activity,
                option_icon, option_text));
    }
}

Answer 1

试试这个，

image.setImageDrawable(getResources().getDrawable(R.drawable.drawable_name));
