Create Custom Button Like Zoom In Android Map

February 9, 2016 by blogmeister·0 Comments

The only way to have a custom button like the zoom buttons in Android map is to make one of your own. The way I did this is to have an XML drawable assigned to the ImageButton. It is pretty simple.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true"
        android:state_enabled="true">
        <shape android:shape="rectangle">
            <corners android:radius="2dp"/>
            <solid android:color="#95cccccc"/>
        </shape>
    </item>
    <item android:state_enabled="true">
        <shape android:shape="rectangle">
            <corners android:radius="2dp"/>
            <solid android:color="#95ffffff"/>
        </shape>
    </item>
</selector>

<item

android:state_pressed="true"

android:state_enabled="true">

</shape>

</item>

</shape>

</item>

</selector>

Then assign this as background to the ImageButton widget. Your image should be assigned to the source attribute.

That’s it!

How To Get Key Hash Of Android App

February 4, 2016 by blogmeister·0 Comments

Forget trying to familiarize those keytool command options. An easier way is to call a method to output the keyhash of the keystore being used in the app.

This is a method from JavaTechIG. Pretty slick.

public static String getKeyHash(Context context) {
PackageInfo packageInfo;
String key = null;
try {
    String packageName = context.getApplicationContext().getPackageName();
    packageInfo = context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_SIGNATURES);
    for (Signature signature : packageInfo.signatures) {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        key = new String(Base64.encode(md.digest(), 0));
    }
} catch (Exception e) {
    e.printStackTrace();
}
return key;
}

public static String getKeyHash(Context context) {

PackageInfo packageInfo;

String key = null;

try {

String packageName = context.getApplicationContext().getPackageName();

packageInfo = context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_SIGNATURES);

for (Signature signature : packageInfo.signatures) {

MessageDigest md = MessageDigest.getInstance("SHA");

md.update(signature.toByteArray());

key = new String(Base64.encode(md.digest(), 0));

}

} catch (Exception e) {

e.printStackTrace();

}

return key;

}

How To Show Bullets In Android TextView

January 16, 2016 by blogmeister·0 Comments

Sadly, <li> is not supported in TextView. Only a few tags are actually supported by the widget so the options are pretty limited. You can either place your HTML code in a WebView or, if you really want to place it inside a TextView, you can use • instead.
