Question

I want to use some views ID’s, and I want a loop to iterate through all of them.
Here’s what I mean:

for (int i = 0;i<10;i++) {
    TextView tv = (TextView) findViewById(R.id.txt+i);
}

Of course it is wrong, but lets say I have in the layout 10 TextViews:

txt0

txt1

txt2

.

.

.

txt9

I want the loop to perform something like this:

TextView tv = (TextView) findViewById(R.id.txt0);
TextView tv = (TextView) findViewById(R.id.txt1);
.
.
.
TextView tv = (TextView) findViewById(R.id.txt+9);

Is it possible??

Thanks!

Answer 1

You can find the ID by name like this:

for(int i=0;i<10;i++){
     int id = getResources().getIdentifier("txt" + i, "id", context.getPackageName());
     TextView tv = findViewById(id);
     // but what here?
}

However, this just assigns a textview 10 times. What are you doing after this? I can’t see how this is useful but perhaps you can build on it.
