我有一场比赛结束后，我保存得分和名称使用alertdialog进入数据库，它很好，但当我点击游戏窗口上的任何地方alertdialog关闭，再次游戏正在工作，我需要在游戏后禁用游戏窗口已结束或alertdialog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);
}
Animatedview：
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;

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);

答案 0 :(得分：6)
您可以使用下面的cancallable方法，
builder.setCancelable(false);
答案 1 :(得分：2)
如果您想阻止setCanceledOnTouchOutside(false)关闭窗口点击但仍希望能够在后退按钮点击时关闭它，则可以使用AlertDialog AlertDialog方法。< / p>
