Activity使用Dialog样式导致点击空白处自动关闭的问题

<resources>
    <style name="Theme.SoundRecorder" parent="@android:style/Theme.Holo.DialogWhenLarge">
        <item name="android:windowCloseOnTouchOutside">false</item>
    </style>
</resources>

YourActivity.this.setFinishOnTouchOutside(false); 

@Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN && isOutOfBounds(this, event)) {
            return true;
        }
        return super.onTouchEvent(event);
    }

    private boolean isOutOfBounds(Activity context, MotionEvent event) {
        final int x = (int) event.getX();
        final int y = (int) event.getY();
        final int slop = ViewConfiguration.get(context).getScaledWindowTouchSlop();
        final View decorView = context.getWindow().getDecorView();
        return (x < -slop) || (y < -slop)|| (x > (decorView.getWidth() + slop))|| (y > (decorView.getHeight() + slop));
    }
