Today’s Learning 1. 2. 3. 4. Splash Screen Home Screen List. View example using Country List Radio. Button example using Education

Splash Screen

Splash Activity XML <Linear. Layout android: orientation="vertical" android: gravity="center“> <Image. View android: src="@drawable/ic_android_black_24 dp" android: layout_width="100 dp" android: layout_height="100 dp" /> <Text. View android: layout_margin. Top="20 dp" android: text="The Great App" android: layout_width="wrap_content" android: layout_height="wrap_content" /> </Linear. Layout>

Splash Screen Coding new Handler(). post. Delayed(new Runnable() { @Override public void run() { Intent i = new Intent(Splash. this, Home. class); start. Activity(i); finish(); } }, 4000);

Home Screen

Home Activity XML <Image. View android: layout_weight="2" android: src="@drawable/ic_android_black_24 dp" android: layout_width="match_parent" android: layout_height="wrap_content" /> <Linear. Layout android: layout_margin="10 dp" android: layout_weight="1" android: layout_width="match_parent" android: layout_height="wrap_content"> <Button android: layout_weight="1" android: text="Button 1" android: layout_width="wrap_content" android: layout_height="match_parent" /> <Button android: layout_weight="1" android: text="Button 2" android: layout_width="wrap_content" android: layout_height="match_parent" /> </Linear. Layout>

List View

List View Activity XML <Text. View android: text. Appearance="? android: text. Appearance. Medium" android: gravity="center_horizontal" android: text="List of Countries" <string-array android: layout_width="match_parent" name="countries"> android: layout_height="wrap_content" /> <item>India</item> <List.

View> <item>USA</item> <item>UK</item> <item>Canada</item> </string-array>

Radio. Button example using Education

Radio. Button Activity XML <Text. View android: text. Style="bold" android: text="Education 1" android: layout_width="match_parent" android: layout_height="wrap_content" /> <Radio. Group android: id="@+id/groupeducation 1" android: layout_width="match_parent" android: layout_height="wrap_content" > <Radio. Button android: id="@+id/radio 1" android: text="SSC" android: layout_width="wrap_content" android: layout_height="wrap_content" /> <Radio. Button android: id="@+id/radio 2" android: text="HSC" android: layout_width="wrap_content" android: layout_height="wrap_content" /> </Radio. Group>

Radio. Button Activity XML <Text. View android: text. Style="bold" android: layout_margin. Top="10 dp" android: text="Education 2" android: layout_width="match_parent" android: layout_height="wrap_content" /> <Radio. Group android: id="@+id/groupeducation 2" android: layout_width="match_parent" android: layout_height="wrap_content" > <Radio. Button android: id="@+id/radio 3" android: text="BCA" android: layout_width="wrap_content" android: layout_height="wrap_content" /> <Radio. Button android: id="@+id/radio 4" android: text="BBA" android: layout_width="wrap_content" android: layout_height="wrap_content" /> <Radio. Button android: id="@+id/radio 5" android: text="Other" android: layout_width="wrap_content" android: layout_height="wrap_content" /> </Radio. Group> <Button android: id="@+id/btnsubmit" android: layout_gravity="center_horizontal" android: text="Submit" android: layout_width="wrap_content" android: layout_height="wrap_content" />

Radio. Button Code int selected. Id=((Radio. Group) find. View. By. Id(R. id. groupeducation 1)). get. Checked. Radio. Butt on. Id(); Radio. Button rb 1 =(Radio. Button)find. View. By. Id(selected. Id); Toast. make. Text(Option 2. this, rb 1. get. Text(), Toast. LENGTH_ SHORT). show(); int selected. Id 2=((Radio. Group) find. View. By. Id(R. id. groupeducation 2)). get. Checked. Radio. Butt on. Id(); Radio. Button rb 2 =(Radio. Button)find. View. By. Id(selected. Id 2); Toast. make. Text(Option 2. this, rb 2. get. Text(), Toast. LENGTH_ SHORT). show();
