android添加arraylist,Java将ArrayList对象添加到Android中的GridView

您的适配器

public class Benildus_Adapter extends ArrayAdapter {

ArrayList list; // your person arraylist

Context context; // the activity context

int resource; // this will be your xml file

public Benildus_Adapter(Context context, int resource,ArrayList objects) {

super(context, resource, objects);

// TODO Auto-generated constructor stub

this.list &＃61; objects;

this.context &＃61; context;

this.resource &＃61; resource;

}

&＃64;Override

public int getCount() {

// TODO Auto-generated method stub

if(list.size() &＃61;&＃61; 0){

return 0;

}else{

return list.size();

}

}

&＃64;Override

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

// TODO Auto-generated method stub

View child &＃61; convertView;

RecordHolder holder;

LayoutInflater inflater &＃61; ((Activity) context).getLayoutInflater(); // inflating your xml layout

if (child &＃61;&＃61; null) {

child &＃61; inflater.inflate(resource, parent, false);

holder &＃61; new RecordHolder();

holder.fname &＃61; (TextView) child.findViewById(R.id.fname); // fname is the reference to a textview

holder.lname &＃61; (TextView) child.findViewById(R.id.lname); // in your xml layout file

holder.bio &＃61;(TextView) child.findViewById(R.id.bio); // you are inflating.etc

child.setTag(holder);

}else{

holder &＃61; (RecordHolder) child.getTag();

}

final Person user &＃61; list.get(position); // you can remove the final modifieer.

holder.fname.setText(user.getFName());

holder.lname.setText(user.getLName());

holder.bio.setText(user.getBiography());

holder.image.setImageBitmap(user.getImage()); // if you use string then you download the image using

// the string as url and set it to your imageview..

return child;

}

static class RecordHolder {

TextView fname,lname,bio;

ImageView image;

}

&＃64;Override

public void notifyDataSetChanged() { // you can remove this..

// TODO Auto-generated method stub

if(getCount() &＃61;&＃61; 0){

//show layout or something that notifies that no list is in..

}else{

// this is to make sure that you can call notifyDataSetChanged in any place and any thread

new Handler(getContext().getMainLooper()).post(new Runnable() {

&＃64;Override

public void run() {

// TODO Auto-generated method stub

Benildus_Adapter.super.notifyDataSetChanged();

}

});

}

}

}

你的人班

public class Person {

private String FName;

private String LName;

private String Biography;

private Bitmap image; // add the image too to your class, you can store the url of the image

// or save it using bitmap.. if you store the url then &＃61; String image; the load the image

// in the getview method.. any way you choose..

public String getFName() {

return FName;

}

public void setFName(String fName) {

FName &＃61; fName;

}

public String getLName() {

return LName;

}

public void setLName(String lName) {

LName &＃61; lName;

}

public String getBiography() {

return Biography;

}

public void setBiography(String biography) {

Biography &＃61; biography;

}

public Bitmap getImage() {

return image;

}

public void setImage(Bitmap image) {

this.image &＃61; image;

}

}

编辑我只是忘了设置适配器.

gridView &＃61; (GridView)findViewById(R.id.grid);

Benildus_Adapter bA &＃61; new Benildus_Adapter(this, R.layout.myxml,dbPersons);

gridView.setAdapter(bA);
