我需要一些帮助来设置android Java源代码的背景图像大小,这里是我想要添加的代码:setBackgroundResource(R.drawable.slider_bg_right);
是我添加的行以添加背景,但是图像尺寸太小,我想编辑背景的大小。
switch (action) {
case MotionEvent.ACTION_DOWN: {
mTracking = true;
mTriggered = false;
vibrate();
if (leftHit) {
mCurrentSlider = mLeftSlider;
mOtherSlider = mRightSlider;
mThreshold = isHorizontal() ? THRESHOLD : 1.0f - THRESHOLD;
setGrabbedState(OnTriggerListener.LEFT_HANDLE);
----- setBackgroundResource(R.drawable.slider_bg_right); -------
} else {
mCurrentSlider = mRightSlider;
mOtherSlider = mLeftSlider;
mThreshold = isHorizontal() ? 1.0f - THRESHOLD : THRESHOLD;
setGrabbedState(OnTriggerListener.RIGHT_HANDLE);
------ setBackgroundResource(R.drawable.slider_bg_left); -------
}
mCurrentSlider.setState(Slider.STATE_PRESSED);
mCurrentSlider.showTarget();
mOtherSlider.hide();
break;
}
}

尝试使用Bitmap.createScaledBitmap();在android中指定所需的宽度和高度。
