Question

我是新的。如果我提出rid笑问题,我会感到ry。

我想有通用的适应班实施<代码>ListAdapter。我必须超越其某些职能,如<代码>。 View。

抵达观望功能是最重要的部分,它是在提供时呼吁的(如p.net(我想))。

我写了以下最简单的措辞:

package com.yeni.listAdapter;

import android.app.ListActivity;
import android.os.Bundle;

public class baslangicAktivitesi extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);
        setListAdapter(new NewAdapter(this));
    }
}

这是我的通用名单A。

package com.yeni.listAdapter;

import android.content.Context;
import android.database.DataSetObserver;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewGroup.LayoutParams;
import android.widget.LinearLayout;
import android.widget.ListAdapter;
import android.widget.TextView;

public class NewAdapter implements ListAdapter {
    private Context ctx;

    public NewAdapter(Context _ctx) {
        super();
        ctx = _ctx;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public int getItemViewType(int arg0) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        TextView tv = new TextView(ctx);
        tv.setText("This text will be shown");

        LinearLayout lila = new LinearLayout(ctx);
        lila.addView(tv,new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));

        return lila;
    }

    @Override
    public int getViewTypeCount() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public boolean hasStableIds() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isEmpty() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public void registerDataSetObserver(DataSetObserver observer) {
        // TODO Auto-generated method stub

    }

    @Override
    public void unregisterDataSetObserver(DataSetObserver observer) {
        // TODO Auto-generated method stub

    }

    @Override
    public boolean areAllItemsEnabled() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isEnabled(int position) {
        // TODO Auto-generated method stub
        return false;
    }
}

我所想的是,名单Adapter机制如何,如果想用xml书写模板(我认为这将是)<代码>res->layout。如何做(综合观点认为,我想写一些图像评论和文字评论?)

非常感谢......

很难理解你所说的话......但我最好的是,你想知道,如何在你的清单工作中使用你自己的习惯<条码>xml。

如您所猜测,制作贵国名单的xml模板,将其储存在您的布局中......

LayoutInflater mInflater = LayoutInflater.from(context);

The following s hacked up edition of the Sample Code i found

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

            // When convertView is not null, we can reuse it directly, there is no need
            // to reinflate it. We only inflate a new View when the convertView supplied
            // by ListView is null.
            if (convertView == null) {
                convertView = mInflater.inflate(R.layout.list_item_icon_text, null);

                TextView tvFoo = (TextView) convertView.findViewById(R.id.text);
                ImageView ivBar = (ImageView) convertView.findViewById(R.id.icon);
            }
            // Bind the data efficiently with the holder.
            tvFoo.setText(/* data at position */);
            ivBar.setImageBitmap(/* image at position*/);

            return convertView;
        }

注:R.layout.list_item_icon_text 系您的习俗。
