android - Get drawable for different screen density at runtime -


i want print sizes of drawables @ run-time. if on hdpi device can print size of hdpi drawables how access to, lets mdpi , xhdpi well? can access drawables resource ids following code:

final class<r.drawable> c = r.drawable.class; final field[] fields = c.getdeclaredfields();  (int = 0, max = fields.length; < max; i++) {     final int resourceid;     try {         resourceid = fields[i].getint(drawableresources);     } catch (exception e) {         continue;     }     /* make use of resourceid accessing drawables here */ }

ok found it, explicitly ask particular density drawable this:

drawable drawable = resources.getdrawablefordensity(id, displaymetrics.density_xhigh);

or preferably version

drawable drawable = resources.getdrawablefordensity(id, displaymetrics.density_xhigh, theme);

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
