Android: Gonflage multiples .XML et des objets sur un seul .XML

Question

Objet: (Running API 8) Programmatically, je suis en train de gonfler le suivant sur une seule mise en page, main.xml

• bg_content1.xml
• bg_content2.xml
• @ + id/img_logo
• @ + id/str_username

Note:

1. @ + id/img_logo est un identifiant d'un ImageView situé dans bg_content3.xml
2. @ + id/str_username est un identifiant d'un TextView situé dans bg_content4.xml
3. S'il vous plaît ne me demandez pas pourquoi je dois gonfler plusieurs mises en page et objets sur l'autre mise en page. J'essaie d'optimiser mes mises en page pour des raisons de maintenabilité.

main.xml

<LinearLayout android:id="@+id/main"> 
</LinearLayout> 

bg_content1.xml

<LinearLayout android:id="@+id/bg_content1"> 
    <TextView 
     android:text:"bg_content1 here" 
     //other attributes omitted 
    </TextView> 
</LinearLayout> 

bg_content2.xml

<LinearLayout android:id="@+id/bg_content2"> 
    <TextView 
     android:text:"bg_content2 here" 
     //other attributes omitted 
    </TextView> 
</LinearLayout> 

bg_content3.xml

<LinearLayout android:id="@+id/bg_content2"> 
    <ImageView 
     android:id:"@+id/img_logo" 
     //other attributes omitted 
    </TextView> 
</LinearLayout> 

bg_content4.xml

<LinearLayout android:id="@+id/bg_content4"> 
    <TextView 
     android:id:"@+id/str_username" 
     //other attributes omitted 
    </TextView> 
</LinearLayout> 

MainActivity.xml

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    LinearLayout container = (LinearLayout) findViewById(R.id.main); 
    LayoutInflater inflater = LayoutInflater.from(this); 
    LinearLayout bg_content = (LinearLayout) inflater.inflate(
     R.layout.bg_content1, null); 
    container.addView(bg_content); 

    bg_content = (LinearLayout) inflater.inflate(
     R.layout.bg_content2, null); 
    container.addView(bg_content); 

    ImageView bg_img = (ImageView) inflater.inflate(R.id.img_logo, null); 
    container.addView(bg_img); 

    TextView bg_str = (TextView) inflater.inflate(R.id.str_username, null); 
    container.addView(bg_str); 

}

solution fournie par @Ikaros J'ai modifié quelques erreurs mineures syntaxiques ci-dessous:

bg_content = (LinearLayout) inflater.inflate(
      R.layout.bg_content3, null); 
container.addView(bg_content); 

ImageView bg_img = (ImageView) bg_content.findViewById(R.id.img_logo); 

bg_content = (LinearLayout) inflater.inflate(R.layout.bg_content4, null); 
    container.addView(bg_content); 

TextView bg_str = (TextView) bg_content.findViewById(R.id.str_username); 

Answer 1

Par exemple, dans:

ImageView bg_img = (ImageView) inflater.inflate(R.id.img_logo, null); 
container.addView(bg_img); 

vous êtes essayer de gonfler un enfant de votre mise en page et je pense que c'est vous erreur r. Vous pouvez essayer quelque chose comme:

LinearLayout linear_layout = (LinearLayout) inflater.inflate(R.layout.bg_content3.xml, null); 
container.addView(linear_layout); 

Si vous avez besoin d'une référence à la ImageView vous pouvez consulter comme:

(ImageView) bg_img = (ImageView) linear_layout.findViewById(R.id.bg_img);
