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>
