我要做一个数独游戏 在GameActivity中我已经从assest中随机读取了一个数独，但是我不知道该如何把这些数字加到九宫格里
public class GameActivity extends Activity{
private Button btn01;
private Button btn02;
private Button btn03;
private GameView gameView;
private Handler handler=new Handler(){
public void handleMessage(android.os.Message msag) {
}
};
private String mQuestionFilename[] = {"easy", "medium", "hard"};
private int[] shudu =new int[9*9];
private enum QuestionLevel {
easy(0), medium(1), hard(2);
private final int value;
public int getValue(){
return value;
}
QuestionLevel(int value){
this.value = value;
}
}
private int getTile(int x,int y) {
return shudu[y*9+x];
}
public String getTileString(int x,int y){
int v=getTile(x, y);
if (v==0) {
return "";
}
else{
return String.valueOf(v);
}
}
private void NewPuzzle(QuestionLevel level){
String filename = mQuestionFilename[level.getValue()];
int row = 0;
try{
InputStream in = this.getResources().getAssets().open(filename);
int count = in.available();
byte[] buff = new byte[count];
in.read(buff);
String []data = EncodingUtils.getString(buff, "UTF-8").split("\n");
in.close();
Random rdm = new Random();
row = Math.abs(rdm.nextInt()) % data.length; // row sometimes <0
String temp = data[row];
int k=0;
for (int i=0; i<81; i++){
String dt = temp.substring(k);
shudu[i]= temp.charAt(k)-'0';
k=k+2;
}
}catch(Exception e){
e.printStackTrace();
}
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game);
gameView=(GameView)findViewById(R.id.gameview);
btn01=(Button)findViewById(R.id.button_1);
btn01.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
final String[] cities = {"Easy", "Medium", "Hard"};
Dialog dlg = new AlertDialog.Builder(GameActivity.this)
.setTitle("请选择难度")
.setItems(cities,new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which){
case 0:
NewPuzzle(QuestionLevel.easy);
break;
case 1:
//NewPuzzle(QuestionLevel.medium);
break;
case 2:
//NewPuzzle(QuestionLevel.hard);
break;
default:
break;
}
}
})
.create();
dlg.show();
}
});
}
}
这个就是画九宫格 和 数字
