Android jigsaw puzzle game development full record 4

Today, we mainly implement our main interface: international practices:

We have already completed the interface on the first day. Today we will implement the interface function,

This interface provides the following functions:

1. display the difficulty of the game: Use popupwindow and select and change the displayed number.

2. display the default picture to be jigsaw puzzle, including a custom image: This is relatively simple, just the simplest application of the GridView.

3. Custom button function: Call the system atlas and camera

4. view records and learn more: this is also a common application requirement and is relatively simple.

The comments are clear. I believe everyone can understand them.

A data adapter is also provided below:

Package com. xys. xpuzzle. adapter; import java. util. list; import android. r. color; import android. content. context; import android. graphics. bitmap; import android. view. view; import android. view. viewGroup; import android. widget. baseAdapter; import android. widget. gridView; import android. widget. imageView;/*** main interface data adapter ** @ author xys **/public class GridPicListAdapter extends BaseAdapter {// ing List private List <Bitmap> picList; private Context context; public GridPicListAdapter (Context context, List <Bitmap> picList) {this. context = context; this. picList = picList;} @ Override public int getCount () {return picList. size () ;}@ Override public Object getItem (int position) {return picList. get (position) ;}@ Override public long getItemId (int position) {return position ;}@ Override public View getView (int position, View convertView, ViewGroup arg2) {ImageView iv_pic_item = null; if (convertView = null) {iv_pic_item = new ImageView (context); // set the layout image iv_pic_item.setLayoutParams (new GridView. layoutParams (80,100); // sets the display ratio type iv_pic_item.setScaleType (ImageView. scaleType. FIT_XY);} else {iv_pic_item = (ImageView) convertView;} iv_pic_item.setBackgroundColor (color. black); iv_pic_item.setImageBitmap (picList. get (position); return iv_pic_item ;}}

The difficulty today is to call the system atlas and camera:

1. The called Intent has been clearly written in the code.

2. When calling the camera, if data is directly returned, it is actually a thumbnail of the returned camera. To get the original image, you need to first save it to the SD card and then get the image. I hope you will pay attention to it.
