我根据屏幕的百分比给出视图高度。但是视图只能获得整数值。如何在不舍入数字的情况下转换整数值。我根据屏幕计算。当double值变为整数值时，屏幕上的舍入为空白。
public class TutorialFragment extends BaseFragment {
private double mScreenHeight;
private double bgBlueHeight;
private double bgGrayHeight;
private double textHeight;
private double mPathHeight;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_tutorial, container, false);
setTutorialPages();
return mView;
}
private void setBackgroundGray() {
ImageView bgGray = (ImageView) mView.findViewById(R.id.bg_gray_tutorial);
bgGray.getLayoutParams().height = (int) bgGrayHeight;
bgGray.requestLayout();
}
private void setBackgroundBlue() {
ImageView bgBlue = (ImageView) mView.findViewById(R.id.tutorial_dotted_blue_bg);
bgBlue.getLayoutParams().height = (int) bgBlueHeight;
bgBlue.requestLayout();
}
private void defaultScreen() {
DefaultScreen.sharedInstance(getContext()).setDefaultScreen();
mScreenHeight = DefaultScreen.sharedInstance(getContext()).getScreenHeight();
bgBlueHeight = mScreenHeight * 0.30;
bgGrayHeight = mScreenHeight * 0.34;
mPathHeight = mScreenHeight * 0.06;
textHeight = mScreenHeight - bgBlueHeight - bgGrayHeight - mPathHeight;
}
private void setText(String text) {
TextView textView = (TextView) mView.findViewById(R.id.txt_tutorial);
textView.setText(text);
textView.getLayoutParams().height = (int) textHeight;
textView.requestLayout();
}
private void setTutorialPages(){
defaultScreen();
setBackgroundBlue();
setBackgroundGray();
setPath();
}
}
