Android UI Factory

Android UI Factory simplifies building of Android UI by reliving you from having to write boilerplate Android UI code.

Instead of writing code like:

	final Button buttonCancel = new Button(this);
	buttonCancel.setText("Cancel");
	buttonCancel.setId(300);
	final RelativeLayout.LayoutParams buttonCancelParams = new RelativeLayout.LayoutParams(
			RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
	buttonCancelParams.topMargin = 20;
	buttonCancelParams.addRule(RelativeLayout.BELOW, buttonOk.getId());
	buttonCancelParams.addRule(RelativeLayout.ALIGN_RIGHT, checkbox2.getId());
	buttonCancelParams.addRule(RelativeLayout.ALIGN_LEFT, checkbox2.getId());
	buttonCancel.setLayoutParams(buttonCancelParams);
	layout.addView(buttonCancel);	

With Android UI Factory the above can be shorten to:

	final Button buttonCancel = layoutFactory.newTextView(new Button(this))
			.setText("Cancel")
			.topMargin(20)
			.below(buttonOk)
			.alignLeft(checkbox2)
			.alignRight(checkbox2)
			.addViewToLayout()
			.view();								

Library source code

The whole library is actually one file: AndroidUIFactory.java

Just copy it to your project.

Example

Below is the full source code of an Android application that is using Android UI Factory.

package com.adko.androiduifactory;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.RelativeLayout;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
	
		final AndroidUIFactory factory = new AndroidUIFactory(this);
	
		final RelativeLayoutFactory layoutFactory = factory.newRelativeLayout()
				.layoutSize(RelativeLayoutFactory.Size.MATCH_PARENT, RelativeLayoutFactory.Size.MATCH_PARENT)
				.align(RelativeLayoutFactory.Align.ALIGN_PARENT_TOP, RelativeLayoutFactory.Align.ALIGN_PARENT_LEFT)
				.viewSize(RelativeLayoutFactory.Size.WRAP_CONTENT, RelativeLayoutFactory.Size.WRAP_CONTENT);
		final RelativeLayout layout = layoutFactory.layout();
	
		final CheckBox checkbox1 = layoutFactory.newTextView(new CheckBox(this))
				.setText("Checkbox 1")
				.topMargin(30)
				.leftMargin(30)
				.addViewToLayout()
				.view();

		final CheckBox checkbox2 = new CheckBox(this);
		checkbox2.setText("Checkbox 2");
		checkbox2.setId(200);
		final RelativeLayout.LayoutParams checkBox2params = new RelativeLayout.LayoutParams(
				RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
		checkBox2params.addRule(RelativeLayout.BELOW, checkbox1.getId());
		checkBox2params.addRule(RelativeLayout.ALIGN_LEFT, checkbox1.getId());
		checkbox2.setLayoutParams(checkBox2params);
		layout.addView(checkbox2);

		final Button buttonOk = layoutFactory.newTextView(new Button(this))
				.setText("OK")
				.topMargin(20)
				.below(checkbox2)
				.alignLeft(checkbox2)
				.alignRight(checkbox2)
				.addViewToLayout()
				.view();
	
		final Button buttonCancel = new Button(this);
		buttonCancel.setText("Cancel");
		buttonCancel.setId(300);
		final RelativeLayout.LayoutParams buttonCancelParams = new RelativeLayout.LayoutParams(
				RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
		buttonCancelParams.topMargin = 20;
		buttonCancelParams.addRule(RelativeLayout.BELOW, buttonOk.getId());
		buttonCancelParams.addRule(RelativeLayout.ALIGN_RIGHT, checkbox2.getId());
		buttonCancelParams.addRule(RelativeLayout.ALIGN_LEFT, checkbox2.getId());
		buttonCancel.setLayoutParams(buttonCancelParams);
		layout.addView(buttonCancel);	
							
		setContentView(layout);
	}
