游戏结束后我有一个游戏，我使用警报对话框将分数和名称保存到数据库中，这很好但是当我单击游戏窗口上的任何位置时警报对话框关闭并且游戏再次运行我需要在游戏后禁用游戏窗口结束或警报对话框从未关闭事件我点击游戏窗口。
我的代码是:
mainactivity:
public class MainActivity extends Activity {
static TextView editText;
static int score=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText=(TextView) findViewById(R.id.editText1);
//editText.setText(""+score);
Button button=(Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new AnimatedView(MainActivity.this).pauseClicked();
}
});
}
public static void setCount(int count) {
//new MainActivity().onCreate(null);
score=count;
editText.setText(""+score);
}
动画 View :
public class AnimatedView extends ImageView{
String name;
static int count=0;
private Context mContext;
int x = 130;
int y = 450;
private float a,b;
private int xVelocity = 20;
private int yVelocity = 20;
private Handler h;
private final int FRAME_RATE = 25;
BitmapDrawable ball;
boolean touching;
boolean dm_touched = false;
float move=3;
int bm_x = 0, bm_y = 0, bm_offsetx, bm_offsety,bm_w,bm_h;
boolean paused;
private Paint line, ball1, background;
static int click=0;
private static final int TEXT_ID = 0;
DBCeation dbCeation;
public AnimatedView(Context context) {
super(context);
}
public AnimatedView(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
h = new Handler();
}
private Runnable r = new Runnable() {
@Override
public void run() {
//Log.e("game","run called");
if(touching = true)
invalidate();
}
};
@Override
protected void onDraw(Canvas c) {
BitmapDrawable ball = (BitmapDrawable) mContext.getResources().getDrawable(R.drawable.ball);
if (x<0 && y <0) {
//x = this.getWidth()/2;
y = c.getHeight()/2;
} else {
//Log.d("s",""+xVelocity);
Log.d("s",""+yVelocity);
x += xVelocity;
y += yVelocity;
if ((x > this.getWidth() - ball.getBitmap().getWidth()) || (x < 0)) {
xVelocity = xVelocity*-1;
}
if (y >( this.getHeight() - ball.getBitmap().getHeight()) ||y <0) {
yVelocity = yVelocity*-1;
}
}
c.drawBitmap(ball.getBitmap(), x, y, null);
//Log.e("sarat",""+touching);
if(click>=2){
if(bm_h+y>630){
final EditText input=new EditText(mContext);
Toast.makeText(getContext(),"game over",Toast.LENGTH_SHORT).show();
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setTitle("Game Is Over");
builder.setMessage("Enter your Name");
// Use an EditText view to get user input.
input.setId(TEXT_ID);
builder.setView(input);
builder.setPositiveButton("save", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
name=input.getText().toString();
Log.d("name",""+name);
int score=MainActivity.score;
dbCeation=new DBCeation(mContext);
dbCeation.insertValues(name, score);

if(touching){

@Override

最佳答案
你可以像下面这样使用它的 cancallable 方法，
builder.setCancelable(false);
