android - 循环内的动态布局充气器

Question

我想根据来自 parcelable 数组的数据循环在 Activity 中显示 x 个 xml 布局。对于此示例，我已将数组大小更改为固定值 3。

我要膨胀的布局的 xml 是:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
    android:id="@+id/tv_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>    
    <RadioGroup android:id="@+id/rg_type"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
    <RadioButton
        android:id="@+id/radioButton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Yes"
        android:tag="1" />
    <RadioButton
        android:id="@+id/radioButton2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="No"
        android:tag="0" />
    <RadioButton
        android:id="@+id/radioButton3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Don't Know"
        android:tag="3" />    
</RadioGroup>
</LinearLayout>

父页面的xml为:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" 
android:layout_height="fill_parent"
android:orientation="vertical"> 
<LinearLayout 
    android:id="@+id/ll_content"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content">
</LinearLayout>
</LinearLayout>

这是 Activity 的代码:

public class PainRecord_FollowUp extends Activity {

LinearLayout llContent;
Context context;
PainDataItem pd_in; //this is the Parcelable extra received

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.painrecord_followup);       

    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        pd_in = extras.getParcelable("m_PainDataItem");
    }        
    LayoutInflater layoutInflator = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    LinearLayout insertPoint = (LinearLayout) findViewById(R.id.ll_content);
    List views = new ArrayList();

    for(int i=0; i<3; i++){
        View view = layoutInflator.inflate(R.layout.row_painrecord_followup, null);
        TextView textView = (TextView) view.findViewById(R.id.tv_title);
        textView.setText("did x help " + i);
        view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
        views.add(view);
    }
    for(int i = 0; i<views.size(); i++)
        insertPoint.addView((View) views.get(i));
}
}

它不是将每个布局显示在彼此下方，而是像这样显示:

如果我更改为 LayoutParams.FILL_PARENT，则只显示 [0] 循环值。

收到的任何建议。

谢谢

将您的 LinearLayout 方向设置为垂直

<LinearLayout
    android:id="@+id/ll_content"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:orientation="vertical">
</LinearLayout>
