Roboguice学习之视图注入

Robuguide的使用

准备工作：

首先在项目中必须实现GreetingModule和RoboguiceDemoApplication

GreetingModule.java

import com.google.inject.AbstractModule;

public class GreetingModule extends AbstractModule {

@Override

protected void configure() {

}

}

RoboguiceDemoApplication.java

import roboguice.application.RoboApplication;

public class RoboguiceDemoApplication extends RoboApplication{

}

在values文件夹下必须出现如下文件：

Roboguice.xml文件中item对应工程中对应的GreetingModule

<?xml version="1.0" encoding="utf-8"?>

<resources>

<string-array name="roboguice_modules">

<item>com.pstreets.roboguice.demo.GreetingModule</item>

</string-array>

</resources>

视图注入：

Activity必须继承实现RoboActivity

Demo如下：

public class InjectViewDemo extends RoboActivity {

@InjectView (R.id.button) Button goButton;

    @InjectView (R.id.textview1) TextView textView1;

    @InjectView (R.id.textview2) TextView textView2;

    @InjectView (R.id.textview3) TextView textView3;

    @InjectView (R.id.textview4) TextView textView4;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.injectview);

goButton.setOnClickListener(mGoListener);

}

private OnClickListener mGoListener = new OnClickListener()

{

public void onClick(View v)

{

textView1.setText("Clicked");

textView2.setText("Clicked");

textView3.setText("Clicked");

textView4.setText("Clicked");

}

};

}

视图界面：

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="match_parent"

android:layout_height="match_parent">

<TextView

android:id="@+id/textview1"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/injectview"

/>

<TextView

android:id="@+id/textview2"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/injectview"

/>

<TextView

android:id="@+id/textview3"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/injectview"

/>

<TextView

android:id="@+id/textview4"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/injectview"

/>

<Button android:id="@+id/button"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center_vertical"

android:text="@string/clickmebutton"/>

</LinearLayout>
