循环内的动态布局充气机 [英] Dynamic layout inflator within a loop
本文介绍了循环内的动态布局充气机的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想基于可拆分数组中的数据循环,在活动中显示xml布局的 x 编号.对于此示例,我将数组大小更改为固定值3.
I want to display x number of an xml layout within an activity based upon a loop of data from a parcelable array. For this example, I've changed the array size to a fixed value of 3.
我要膨胀的布局的xml是:
The xml of the layout I am wanting to inflate is:
<?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是:
<?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>
这是活动的代码:
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));
}
}
与其显示每个布局彼此之间的位置,不如显示以下内容:
Instead of showing each layout underneath each other, it displays it like this:
如果我更改为LayoutParams.FILL_PARENT,则仅显示[0]循环值.
If I change to LayoutParams.FILL_PARENT, then just the [0] loop value shows.
任何收到的建议都很好.
Any advice greatly received.
谢谢
推荐答案
将LinearLayout方向设置为垂直
Set your LinearLayout orientation to vertical
<LinearLayout
android:id="@+id/ll_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
