I'm new to android.
I've found some code for creating a quick action menu in android.
With this code you can click on the 3 buttons "Size, Bold and Italic". But I want to make them checkable, so when you click bold it becomes active instead of flashing the button click.
Activity.class:
public class CreateActivity extends AppCompatActivity {
private static final int ID_SIZE = 1;
private static final int ID_BOLD = 2;
private static final int ID_ITALIC = 3;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create);
ActionItem sizeItem = new ActionItem(ID_SIZE, "Headline", getResources().getDrawable(R.drawable.size_icon));
ActionItem boldItem = new ActionItem(ID_BOLD, "Bold", getResources().getDrawable(R.drawable.bold_icon));
ActionItem italicItem = new ActionItem(ID_ITALIC, "Italic", getResources().getDrawable(R.drawable.italic_icon));
sizeItem.setSticky(true);
boldItem.setSticky(true);
italicItem.setSticky(true);
final QuickAction mQuickAction = new QuickAction(this);
mQuickAction.addActionItem(sizeItem);
mQuickAction.addActionItem(boldItem);
mQuickAction.addActionItem(italicItem);
//setup the action item click listener
mQuickAction.setOnActionItemClickListener(new QuickAction.OnActionItemClickListener() {
@Override
public void onItemClick(QuickAction quickAction, int pos, int actionId) {
ActionItem actionItem = quickAction.getActionItem(pos);
switch (actionId) {
case ID_SIZE:
Toast.makeText(getApplicationContext(), "Size item selected", Toast.LENGTH_SHORT).show();
case ID_BOLD:
Toast.makeText(getApplicationContext(), "Bold", Toast.LENGTH_SHORT).show();
default:
Toast.makeText(getApplicationContext(), actionItem.getTitle() + " selected", Toast.LENGTH_SHORT).show();
}
}
});
mQuickAction.setOnDismissListener(new QuickAction.OnDismissListener() {
@Override
public void onDismiss() {
Toast.makeText(getApplicationContext(), "Ups..dismissed", Toast.LENGTH_SHORT).show();
}
});
ImageButton textPropertiesButton = (ImageButton) this.findViewById(R.id.textPropertiesButton);
textPropertiesButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mQuickAction.show(v);
}
});
}
}
