如何加载从资源中的文件夹图像变成ListView的机器人 [英] how to load images from resources folder into android listview

问题描述

我有一个200图像资源文件夹我命名他们为 name_1.png ， name_2.png 。我有一个数组中，我有几个数字，如 2，4，6，30，40 ...等等。

我想加载图像与文本视图到安卓列表视图，并根据从资源文件夹的数量显示图像。

为此，我创建了一个活动类和图像适配器类为自定义列表查看。

我能够根据阵列数据的数字显示文本视图数据，但没有图像。

任何一个可以建议我如何做到这一点。我想，我必须写在 getview 方法code改变形象。

这是我试过 getview 法

  @覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
    convertView = mInflater.inflate（mViewResourceId，NULL）;
    TextView的TV1 =（TextView中）convertView.findViewById（R.id.tvtype）;
    TextView中TV2 =（TextView中）convertView.findViewById（R.id.tvnumber）;
    ImageView的I1 =（ImageView的）convertView.findViewById（R.id.ivlfirst）;
    // INT I =的Integer.parseInt（正常_+ mStrings.get（位置）+PNG）;i1.setBackgroundResource（正常_+ mStrings.get（位置）+PNG）;
    tv1.setText（mStrings1.get（位置））;
    tv2.setText（mStrings.get（位置））;
    返回convertView;
}
 

解决方案

需要一个整数数组为 R.drawable.imageView1 .... ..200 ，并通过它的价值如同

 私人整数[] = Imgid {R.drawable.imageview1，...，200};
    i1.setBackgroundResource（Imgid [J]）;
 

I have a 200 images in resource folder i named them as name_1.png,name_2.png. and I have a array in that I have few numbers such as 2, 4 , 6 ,30 , 40 ... and so on.

I want to load image and text view into android listview and show the images according to the number from resource folder.

For this I have created a activity class and image adapter class for custom list view.

I am able to show the text view data but not the images according to the array data numbers .

can any one suggest me how to do this. I am thinking that I have to write code in getview method to change the image.

This is getview method that I tried

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


    TextView tv1 = (TextView)convertView.findViewById(R.id.tvtype);
    TextView tv2 = (TextView)convertView.findViewById(R.id.tvnumber);
    ImageView i1= (ImageView)convertView.findViewById(R.id.ivlfirst);
    //int i = Integer.parseInt("normal_"+mStrings.get(position)+".png");

i1.setBackgroundResource("normal_"+mStrings.get(position)+".png");
    tv1.setText(mStrings1.get(position));
    tv2.setText(mStrings.get(position));
    return convertView;
}

解决方案

Take One Integer array for R.drawable.imageView1......200 and pass its value Like

    private Integer[] Imgid = {R.drawable.imageview1,....,200  };
    i1.setBackgroundResource(Imgid[j]);
