Membuat Aplikasi Android Sederhana Menggunakan Button, TextView, ImageView dan Animation
- Buat splash_screen.xml untuk tampilan awal aplikasi seperti dibawah ini:
<?xml version=“1.0” encoding=“utf-8”?>
<RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background=“#0844d5” >
<ImageView
android:id=“@+id/logoId”
android:layout_width=“wrap_content”
android:layout_height=“wrap_content”
android:layout_alignParentBottom=“true”
android:layout_alignParentLeft=“true”
android:layout_marginBottom=“5dp”
android:layout_marginLeft=“10dp”
android:src=“@raw/logoid” />
<ImageView
android:id=“@+id/logoSt”
android:layout_width=“170dp”
android:layout_height=“170dp”
android:layout_centerHorizontal=“true”
android:layout_centerVertical=“true”
android:src=“@raw/logo” />
</RelativeLayout>
- Buat SplashScreen.java seperti dibawah ini:
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.Menu;
import android.view.MenuItem;
import android.view.Window;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
public class SplashScreen extends ActionBarActivity {
private Animation anim1, anim2;
private ImageView logoSt, logoId;
private Handler handlerTimer = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.splash_screen);
anim1 = AnimationUtils.loadAnimation(this, R.anim.logo);
anim2 = AnimationUtils.loadAnimation(this, R.anim.logo);
Thread splash = new Thread() {
public void run() {
logoSt = (ImageView) findViewById(R.id.logoSt);
logoSt.setImageResource(R.drawable.ic_launcher);
logoSt.startAnimation(anim1);
handlerTimer.postDelayed(new Runnable() {
@Override
public void run() {
logoId = (ImageView) findViewById(R.id.logoId);
logoId.setImageResource(R.raw.logoid);
logoId.startAnimation(anim2);
}
}, 500);
try {
sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Intent menu = new Intent(“com.interactivedeveloper.simpletext.MAIN”);
startActivity(menu);
finish();
}
};
splash.start();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.splash_screen, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
- Buat tampilan main.xml seperti dibawah ini:
<?xml version=“1.0” encoding=“utf-8”?>
<RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”
android:layout_width=“match_parent”
android:layout_height=“match_parent” >
<RelativeLayout
android:id=“@+id/relativeLayout1”
android:layout_width=“fill_parent”
android:layout_height=“wrap_content”
android:layout_below=“@+id/hijau”
android:layout_centerHorizontal=“true”
android:gravity=“center” >
<ImageView
android:id=“@+id/show”
android:layout_width=“100dp”
android:layout_height=“30dp”
android:src=“@raw/show” />
<ImageView
android:id=“@+id/clear”
android:layout_width=“100dp”
android:layout_height=“30dp”
android:layout_toRightOf=“@+id/show”
android:src=“@raw/clear” />
</RelativeLayout>
<ImageView
android:id=“@+id/ungu”
android:layout_width=“50dp”
android:layout_height=“50dp”
android:layout_alignTop=“@+id/hijau”
android:layout_toLeftOf=“@+id/merah”
android:src=“@raw/ungu” />
<ImageView
android:id=“@+id/merah”
android:layout_width=“50dp”
android:layout_height=“50dp”
android:layout_alignTop=“@+id/hijau”
android:layout_marginLeft=“5dp”
android:layout_toLeftOf=“@+id/hijau”
android:src=“@raw/merah” />
<ImageView
android:id=“@+id/biru”
android:layout_width=“50dp”
android:layout_height=“50dp”
android:layout_alignTop=“@+id/hijau”
android:layout_marginRight=“5dp”
android:layout_toRightOf=“@+id/hijau”
android:src=“@raw/biru” />
<ImageView
android:id=“@+id/kuning”
android:layout_width=“50dp”
android:layout_height=“50dp”
android:layout_alignTop=“@+id/hijau”
android:layout_toRightOf=“@+id/biru”
android:src=“@raw/kuning” />
<ImageView
android:id=“@+id/hijau”
android:layout_width=“50dp”
android:layout_height=“50dp”
android:layout_centerHorizontal=“true”
android:layout_centerVertical=“true”
android:layout_margin=“5dp”
android:src=“@raw/hijau” />
<TextView
android:id=“@+id/text”
android:layout_width=“wrap_content”
android:layout_height=“wrap_content”
android:layout_above=“@+id/hijau”
android:layout_centerHorizontal=“true”
android:layout_margin=“10dp”
android:gravity=“center”
android:textSize=“18sp” />
<TextView
android:id=“@+id/hint”
android:layout_width=“wrap_content”
android:layout_height=“wrap_content”
android:layout_alignParentBottom=“true”
android:layout_centerHorizontal=“true”
android:layout_margin=“2dp”
android:gravity=“center”
android:text=“Tekan tomboh Show! untuk memasukkan text” />
</RelativeLayout>
