Hello Friends, today I am going to share steps to create a simple Google watch demo to show current time and date using java.util-
1)Open Android Studio IDE and update it to API Level 20.
2)Create New Project
3)Choose Android Wear project
4)Now by default IDE will create MainActivity.java and activity_main.xml, rect_activity_main.xml, round_activity_main.xml
5)Now open your MainActivity.java and set text value-
mTextView.setText(String.valueOf(new Date()));
Full Code:
1)MainActivty.java
package demo.watch.androidhub4you.com.androidwatch;
import android.app.Activity;
import android.os.Bundle;
import android.support.wearable.view.WatchViewStub;
import android.widget.TextView;
import java.util.Date;
public class MainActivity extends Activity {
private TextView mTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
@Override
public void onLayoutInflated(WatchViewStub stub) {
mTextView = (TextView) stub.findViewById(R.id.text);
mTextView.setText(String.valueOf(new Date()));
}
});
}
}
2)activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.wearable.view.WatchViewStub
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/watch_view_stub"
android:layout_width="match_parent" android:layout_height="match_parent"
app:rectLayout="@layout/rect_activity_main" app:roundLayout="@layout/round_activity_main"
tools:context=".MainActivity"
tools:deviceIds="wear"></android.support.wearable.view.WatchViewStub>
3)round_activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<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" tools:context=".MainActivity" tools:deviceIds="wear_round">
<TextView android:id="@+id/text" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_centerHorizontal="true"
android:layout_centerVertical="true" android:text="@string/hello_round" />
</RelativeLayout>
4)rect_activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:orientation="vertical"
tools:context=".MainActivity" tools:deviceIds="wear_square">
<TextView android:id="@+id/text" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="@string/hello_square" />
</LinearLayout>
Thanks,
