i am new to Android Development.I have created an applicaiton which will display the corresponding textview on clicking a textview.
For that i have given a if-else-if ladder condition statement to display the textview. Since i have lot of textviews(around 100), while building the project android studio is saying CODE IS TOO LONG.
How to solve this issue. Is it possible to use the MAP to iterate through the textview IDS?
Please help me.
public void click(View v) {
switch (v.getId()) {
case R.id.fam:
// check if a child is set to a specific String
String toSearchFor = "badaatext";
boolean found = false;

for (View child : allViewsWithinMyTopView) {
if (child instanceof TextView) {
TextView childTextView = (TextView) child;
int intName = childTextView.getId();
System.out.println("The Child TextView is : " + childTextView.getResources().getResourceEntryName(intName));
if (childTextView.getResources().getResourceEntryName(intName).startsWith("badaatext")) {
found = true;
System.out.println("The text is foudn inside the layout");
System.out.println("And the Textview ID is :" + childTextView.getResources().getResourceEntryName(intName));
childTextView.setVisibility(View.GONE);
