you can still achieve auto-resizing of text in a TabLayout by calculating the desired font size based on the width of the tab and the length of the text, and then setting the font size using a SpannableString. Here is an example implementation:
public class MainActivity extends AppCompatActivity {
private TabLayout tabLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabLayout = findViewById(R.id.tab_layout);
// Add tabs to TabLayout
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
// Set TabLayout listener
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
// Add your code here
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
// Add your code here
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
// Add your code here
}
});
// Auto resize text in tabs
autoResizeTabText();
}
private void autoResizeTabText() {
for (int i = 0; i < tabLayout.getTabCount(); i++) {
TabLayout.Tab tab = tabLayout.getTabAt(i);
if (tab != null) {
// Get tab text
String tabText = tab.getText().toString();
// Get tab width
int tabWidth = calculateTabWidth(tabLayout, i);
// Calculate desired font size
int fontSize = calculateFontSize(tabText, tabWidth);
// Create SpannableString with resized font size
SpannableString spannableString = new SpannableString(tabText);
spannableString.setSpan(new AbsoluteSizeSpan(fontSize), 0, spannableString.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);
// Set tab text with resized font size
tab.setText(spannableString);
}
}
}
private int calculateTabWidth(TabLayout tabLayout, int position) {
View tabView = ((ViewGroup) tabLayout.getChildAt(0)).getChildAt(position);
return tabView.getWidth();
}
private int calculateFontSize(String text, int width) {
Paint paint = new Paint();
Rect bounds = new Rect();
int fontSize = 100;
paint.setTextSize(fontSize);
paint.getTextBounds(text, 0, text.length(), bounds);
while (bounds.width() > width) {
fontSize--;
paint.setTextSize(fontSize);
paint.getTextBounds(text, 0, text.length(), bounds);
}
return fontSize;
}
}
In this implementation, the autoResizeTabText() method iterates through each tab in the TabLayout and calculates the desired font size based on the width of the tab and the length of the text. It then creates a SpannableString with the resized font size and sets the tab text using the setText() method.
The calculateTabWidth() method calculates the width of a tab by getting the tab view from the TabLayout and using its getWidth() method. The calculateFontSize() method calculates the desired font size by starting with a large font size and decreasing it until the text fits within the tab width.
