在Android中获取屏幕尺寸[重复]

Question

因为有两种方法可以获得尺寸。从13级以上的API来看，这种方法对我很有效

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

14岁以下，这种方法对我有效

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

我可以得到所有API级别的屏幕大小吗？？？请帮帮我。

Answer 1

要支持所有版本的android，请使用以下代码

int Measuredwidth = 0;
int Measuredheight = 0;
Point size = new Point();
WindowManager w = getWindowManager();

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2){
    w.getDefaultDisplay().getSize(size);
    Measuredwidth = size.x;
    Measuredheight = size.y; 
}else{
    Display d = w.getDefaultDisplay(); 
    Measuredwidth = d.getWidth(); 
    Measuredheight = d.getHeight(); 
}

Answer 2

public void ScreenSize()
{
 int Measuredwidth = 0;
    int Measuredheight = 0;
    Point size = new Point();
    WindowManager w = getWindowManager();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2)
    {
        w.getDefaultDisplay().getSize(size);

        Measuredwidth = size.x;
        Measuredheight = size.y;
    }
    else
    {
        Display d = w.getDefaultDisplay();
        Measuredwidth = d.getWidth();
        Measuredheight = d.getHeight();
    }
}

跟这哥们试试

int density;
    private DisplayMetrics metrics;
    private int widthPixels;
    private float scaleFactor;
    private float widthDp;
private DisplayMetrics metrics;
          metrics = new DisplayMetrics();
     getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);

     density= getResources().getDisplayMetrics().densityDpi;

     widthPixels = metrics.widthPixels;

     scaleFactor = metrics.density;

     widthDp = widthPixels / scaleFactor;
