Accessing Resources Through Ids In A Loop

I have long list of EditText elements in a layout actually these are for taking matrix inputs and matrix size can vary 3x3 5x5 ... The ids of the elements are in a series pattern l

Solution 1:

I do something like that. I have 6 variations of resources in one place I need to read.

for (int i = 0; i < 6; i++ ){
          String fname = "p" + i;
          intid = context.getResources().getIdentifier(fname, "drawable", "com.example.yourproject");
          if (id == 0) {
              Log.e(TAG, "Lookup id for resource '"+fname+"' failed");
              // graceful error handling code here
          }
         scoresBm[i] =  (Bitmap) BitmapFactory.decodeResource(context.getResources(), id);

  }

Solution 2:

Better Approach

Example for accessing raw resources.

ArrayList<Integer> id = new ArrayList<Integer>();
for (int i = 0; i <= 10; i++) {
  id.add(getResources().getIdentifier("d"+i, "raw", getPackageName()));
}

Solution 3:

its better to do it pragmatically for example create new xml Layout

layout.xml content only

<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/parent"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical" ></LinearLayout>

now in your activity add views to the layout for loop example

LinearLayoutparent= (LinearLayout) findViewById(R.id.parent);

for(int i=0;i<10;i++)
{
   EditTextetext=newEditText(this);
   //the Id and Tag must be set to call it back if we need info from this field
   etext.setId(i);
   etext.setTag("kernel"+i);
   //add edit text info here such as values and h/w etc
   etext.setText("my id : "+i+" , My Tags is : t"+i);

   //now add EditText field to parent
   parent.addView(etext);
}

and to call any EditText or any other view was added pragmatically , you can call it from tag or id for example

//getlast element added from loop by id
 EditText last= (EditText) parent.findViewById(10);
 //orgetby tag 
 EditText last= (EditText) parent.findViewWithTag("kernel10");

hope this help
