In order to create OptionsMenu in Sketchware, follow the steps given below.
1. Create a more Block extra in your project.
2. To define this more block extra use an add source directly block and put following code in it.
}
@Override
public boolean onCreateOptionsMenu (Menu menu){
menu.add(0, 0, 0, "Item 1");
menu.add(0, 1, 1, "Item 2");
menu.add(0, 2, 2, "Item 3");
return true;
}
Note that here the first } closes more block. Rest of the code is outside the more block extra. This is to code for onCreateOptionsMenu where three items are added to the menu.
Also note that 0, 1, and 2 are Id of the items added to the menu, and Item 1, Item 2, Item 3 are the title of the items added. Change the titles to whatever you want.
To display the OptionsMenu items as icons on the ActionBar, add the id of the images to the menu items. Suppose ic_settings_white is the icon for item 1. Then the code above will change as below.
3. After this add another add source directly block and put following code in it.
@Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()){
case 0:
showMessage("Item 1 Clicked");
break;
case 1:
showMessage("Item 2 Clicked");
break;
case 2:
showMessage("Item 3 Clicked");
break;
case android.R.id.home:
showMessage("Home Button Clicked");
break;
}
return super.onOptionsItemSelected(item);
This is the code for onOptionsItemSelected. The app will show the messages as written in the code when any item from the OptionsMenu is selected.
Note that showMessage("Text"); works only in Sketchware and it is a short form of Toast messages.
4. Suppose you have three more pages apart from main.xml, namely page1.xml, page2.xml andpage3.xml. In order to open these when items in OptionsMenu are selected, follow the steps below.
a. Add three new More Blocks move1, move2, and move3.
b. Add an Intent component intent.
c. Define the more blocks. Use Intent setScreen blocks to move to different screens. See images below.
d. Now add the more blocks in the code at paragraph 2 above. The code for onOptionsItemSelected should now look as given below.
@Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()){
case 0:
_move1();
break;
case 1:
_move2();
break;
case 2:
_move3();
break;
}
return super.onOptionsItemSelected(item);
5. If you want to enable 'home' button in Action Bar alongwith the OptionsMenu, follow the steps given below.
a. Add an add source directly block at the beginning of onCreate event, then put following code in it.
getActionBar().setDisplayHomeAsUpEnabled(true);
And to change the icon add icon ic_dehaze_white using Image manager and then add following after the code above.
b. Now in more Block extra, in onOptionsItemSelected add the case of selecting home button. The code for onOptionsItemSelected should now look as given below.
@Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()){
case 0:
_move1();
break;
case 1:
_move2();
break;
case 2:
_move3();
break;
case android.R.id.home:
showMessage("Home Button Clicked");
break;
}
return super.onOptionsItemSelected(item);
6. Save and Run the project. Now you can see the home button as well as the OptionsMenu on the ActionBar.

Suppose the five number variables are named as h , m ,...
To create an EditText with animation features, we can use the EditText in a TextInputLayout which is a Layout interface in android.support.design.widget library. In Sketchware we cannot add it in xml file but we can create it programmatically. Follow the instructions given below for a simple example. 1. In VIEW area of your project add two Linear horizontal linear2 and linear3 , and a Button button1 . 2. Switch On AppCompat and design. 3. Create a more block extra and define the block using an add source directly block. Put following code in it. } EditText edittext1, edittext2; { Here we declare two EditText fields, edittext1 and edittext2 . 4. In onCreate event, i. Use add source directly block and use codes to define edittext1, set it's LayoutParams, set it's hint, and set it's text color. edittext1 = new EditText(this); edittext1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayou...
We can highlight a particular searched character sequence in a TextView or EditText field or any other text field by using Spannable. To use Spannable class to highlight a searched text in Sketchware Android Project, follow the steps given below. 1. In VIEW area of your project, add an EditText field ( edittext1 ) which will act as input field for search term. Add a TextView ( textview1 ) which will display the number of results found. And add another TextView ( textview2 ) or EditText (edittext2) field which will contain the text in which the word is to be searched. 2. In LOGIC area, in onCreate event set the text to be searched in TextView field. 3. If you want the app to search from any text added by user, use EditText instead textview2 in step no.1 and do not set the text in onCreate. 4. Add a new String variable text . Add three number variables total, len and y . 4. Add a new event edittext1 onTextChanged . 5. In the event edittext1 onTextChange...

How to enable download in an app created with Sketchware? Suppose you have created an app in Sketchware which uses webview to open a site. You can seamlessly explore the site in your app. But the download links in the webview field do not work. But it is possible to make it work by exporting the source code. You can edit the code in either Android studio or Eclipse to add your desired features and then recompile it. I tried to do that but soon realized that setting up environment for development of Android app is not easy for a naive like me. But it can be done by code injection or by using another mobile app called Anacode. Enabling download from webview in Sketchware using add source directly block. 1. In VIEW area of your app insert a WebView (webview1). 2. In LOGIC area, in onCreate event, a. Add write String... to file path ... Block. This will add WRITE_EXTERNAL_STORAGE permission. b. Then add an add source directly block. In this block pu...
