Simple Programming Tutorials Android

The following will mapView I demonstrated the use of the android.
in the example project, I use the build target is the Google APIs 2.1 (on any version of the android is usually always there are two, namely the Android version of its own [* Android 2.1] and the other version I call the banality that is the complete version of his version of the Google APIs).

- google map

1. as usual, is a rare early UI design in res / layout / main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@android:color/transparent"
    android:orientation="vertical" >

    <com.google.android.maps.MapView
            android:id="@+id/mapView"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:apiKey="0fxNRcieQrs_eyjIV6eNWt48wW0hOlCbBsBx3Mw"
            android:background="@android:color/transparent"
            android:clickable="true"
            android:enabled="true" />
</LinearLayout>  


2. Now we create a script to run our application folder

 package com.postedpage.LoadMap;
import com.google.android.maps.MapActivity;

import android.os.Bundle;

public class LoadMapActivity extends MapActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        MapView mapView = (MapView)findViewById(R.id.mapView);
        mapView.displayZoomControls(true);
        mapView.getController().setZoom(8);
        String context = Context.LOCATION_SERVICE;
    LocationManager locationManager = (LocationManager) getSystemService(context);
    String provider = locationManager.GPS_PROVIDER;
    Location location = locationManager.getLastKnownLocation(provider);
        double lat = location.getLatitude();
    double lang = location.getLongitude();
        mapView.getController().setCenter(
    new GeoPoint((int) (lat * 1E6),
        (int) (lang * 1E6)));
    mapView.invalidate();
    }

    @Override
    protected boolean isRouteDisplayed() {
    return false;
    }
}  


3. The final step is setting the permissions on AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.postedpage.LoadMap"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="7" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".LoadMapActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-library android:name="com.google.android.maps"/>
    <uses-permission android:name="android.permission.INTERNET"/>
</manifest>   


- Displays web pages in android 

1. first we will design the UI xml his (res / layout / main.xml).

PHP Code:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <WebView  xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/mywebview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
    />

</LinearLayout>   

2. after we make a simple design, then we will begin to make the main script

PHP Code:

package com.postedpage.WebviewExample;
import android.app.Activity; import android.os.Bundle; import android.webkit.WebView;

public class WebviewExampleActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        WebView webView = (WebView) findViewById(R.id.mywebview); //deklarasi yg akan merujuk ke UI xml kita
        webView.getSettings().setJavaScriptEnabled(true); //setting untuk meperbolehkan javascript pada webview untuk page yg akan di load
        webView.loadUrl("http://www.postedpage.com"); //webview load halaman dari postedpage.com
    }
}  

3. Last step is setting the permissions on the Internet for applications that are located on the "AndroidManifest.xml"
Spoiler for AndroidManifest.xml:

PHP Code:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.postedpage.WebviewExample"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-sdk android:minSdkVersion="7" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".WebviewExampleActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
