RoboBinding使うまで

RoboBinding使うまでにはまったのでメモ。

appの中のbuild.gradleに対して以下の記述を追記します。

apply plugin: 'com.android.application'

// 追記ここから
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
         classpath 'com.neenbedankt.gradle.plugins:android-apt:1.+'
    }
}

apply plugin: 'com.neenbedankt.android-apt'
// 追記ここまで

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.kazuki.myapplication"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
// 追記ここから
    compile"org.robobinding:robobinding:0.8.9"

    apt "org.robobinding:codegen:0.8.9"
// 追記ここまで
}

あとは、getting startでもみて適当にViewModelこしらえて

package com.example.kazuki.myapplication;

import org.robobinding.annotation.PresentationModel;
import org.robobinding.presentationmodel.HasPresentationModelChangeSupport;
import org.robobinding.presentationmodel.PresentationModelChangeSupport;

/**
 * Created by Kazuki on 2015/01/07.
 */
@PresentationModel
public class MainViewModel implements HasPresentationModelChangeSupport {

    private PresentationModelChangeSupport support = new PresentationModelChangeSupport(this);

    private String message = "Hello robobinding.";

    public void sayHello() {
        this.setMessage("こんにちは世界");
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
        this.support.firePropertyChange("message");
    }

    @Override
    public PresentationModelChangeSupport getPresentationModelChangeSupport() {
        return this.support;
    }
}

Viewとバインドして

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    xmlns:bind="http://robobinding.org/android"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <TextView android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        bind:text="{message}"
        android:id="@+id/textView" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Button"
        android:id="@+id/button"
        android:layout_below="@+id/textView"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        bind:onClick="sayHello"/>

</RelativeLayout>

Activityで紐づける。

package com.example.kazuki.myapplication;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.RelativeLayout;

import org.robobinding.binder.Binders;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        MainViewModel vm = new MainViewModel();
        View view = Binders.inflateAndBind(this, R.layout.activity_main, vm);
        setContentView(view);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

gradle弱者なので、gradleの設定に凄い手間取った。
