In this tutorial we will learn How to use Analogclock And Digitalclock  in Android Using Android Studio.

So lets create a project.

Step 1  – Create new Android project

Step 2 – Add a Analogclock And Digitalclock in the main activity. Also Add a button to the main activity as shown in the picture below.

src/main/AndroidManifest.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <AnalogClock
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/analogClock"
        android:layout_below="@+id/digitalClock"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="35dp" />

    <DigitalClock
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/digitalClock"
        android:layout_toEndOf="@+id/button"
        android:layout_alignParentTop="true"
        android:layout_alignLeft="@+id/analogClock"
        android:layout_alignStart="@+id/analogClock" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Swap Clock"
        android:id="@+id/button"
        android:layout_below="@+id/analogClock"
        android:layout_alignLeft="@+id/analogClock"
        android:layout_alignStart="@+id/analogClock"
        android:layout_marginTop="86dp" />

</RelativeLayout>

        digital = (DigitalClock)findViewById(R.id.digitalClock);

                        } else {

                            analog.setVisibility(AnalogClock.VISIBLE);
                        }
                    }
                }
        );

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}
