if(c==cmdjisuan){
this.jisuan(Double.parseDouble(tf1.getString()), Double.parseDouble(tf2.getString()),Double.parseDouble(tf3.getString()),Double.parseDouble(tf4.getString()));

}
public void jisuan(double a , double b, double c, double d){
a = Double.parseDouble(tf1.getString());
b = Double.parseDouble(tf2.getString());
c = Double.parseDouble(tf3.getString());
d = Double.parseDouble(tf4.getString());

double value = 0;

value = (b*2-a*1.5)/c;

tf5.setString(Double.toString(value));
}

Answer 2
