機器人：充氣多個.XML和對象到一個單一的.XML

對象： （運行API 8）編程，我試圖膨脹以下到一個單一的佈局，main.xml中機器人：充氣多個.XML和對象到一個單一的.XML

bg_content1.xml
bg_content2.xml
@ + ID/img_logo
@ + ID/str_username

注：

@ + ID/img_logo是位於bg_content3.xml一個的ImageView的一個id
@ + ID/str_username是位於bg_content4.xml
請不要問我爲什麼要將多個佈局和對象充氣到另一個佈局上。我正在嘗試優化我的佈局以實現可維護性目的。

main.xml中

<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);

}

解決方案提供了一種通過@Ikaros 我已經修改了下面一些小的語法錯誤：

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);

我知道你編程的說，但存在標籤中的XML允許您重複使用佈局 – Patrick

例如在：

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

你試圖誇大你的佈局的孩子，我認爲這是你r錯誤。您可以嘗試類似：

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

如果您需要將ImageView的你可以參考它作爲一個參考：

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