how to create an array string to print list of elements in android

Question

Here I am going to print all the methods that are inside the class using reflection, so in a normal JAVA program it is going to print. But in Android layout it is displaying only one method:

public static void main() throws Exception{
    Log.i("Ramu","I am here displayM ");
    Class o =Class.forName("android.view.AbsSavedState");
    Method M[]=o.getMethods();
    for( i=0;i<M.length;i++)
        methodname = M[i].getName();
    Listview.your_array_list.add(methodname);
    Listview.your_array_list.add(methodname);
    Log.i("Ramu","methode name "+ M[i].getName());
    //System.out.println(M[i].getName());
}

Are you aware that you will only get the last methode stored in M with that for loop ? for( i=0;i<M.length;i++) methodname = M[i].getName(); — Remi878

Your loop ended the very next line of declaration and also u were printing only method name at at final index value after the loop completion. Try using braces, that will solve the problem. Check following code

public static void main() throws Exception{
    Log.i("Ramu","I am here displayM ");
    Class o =Class.forName("android.view.AbsSavedState");
    Method M[]=o.getMethods();
    for( i=0;i<M.length;i++){
        methodname = M[i].getName();
    Listview.your_array_list.add(methodname);
    Listview.your_array_list.add(methodname);
    Log.i("Ramu","methode name "+ M[i].getName());
}

    //System.out.println(M[i].getName());
}

u forgot { } of for loop dude just keep it in { } and then try

for( i=0;i<M.length;i++)
{

        methodname = M[i].getName();
    Listview.your_array_list.add(methodname);
     Log.i("Ramu","methode name "+ M[i].getName());
}

You've forgot to put the brackets, that's you don't get expected output:

Class o = Class.forName("android.view.AbsSavedState");
Method M[] = o.getMethods();
for (int i = 0; i < M.length; i++) {
    methodname = M[i].getName();
    Listview.your_array_list.add(methodname);
    Log.i("Ramu", "method name " + methodname);
}
