在另一个布局中以编程方式扩展布局

Question

我需要帮助我的Android应用程序。我需要在另一个布局中膨胀布局，我不知道我是怎么做的。我的xml代码是这样的：

• item.xml - 我需要膨胀多个xml（取决于变量号）

      <RelativeLayout
           android:id="@+id/cartel_N1"
           android:layout_width="150dp"
           android:layout_height="match_parent"
           android:background="@color/tabhost_background_pressed"

              android:layout_marginTop="7dp" />
  
      </RelativeLayout>

• 这是我的主要xml：

  <ScrollView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
  
    <LinearLayout
         android:id="@+id/container_destacado"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:orientation="vertical" >
  
             <!-- Inflate multiple xml file here -->
  
        </LinearLayout>
  </ScrollView>

Answer 1

你可以用类似的东西

LayoutInflater inflater = LayoutInflater.from(context);

//to get the MainLayout
View view = inflater.inflate(container_destacado, null);
...
//Avoid pass null in the root it ignores spaces in the child layout

View inflatedLayout= inflater.inflate(R.layout.yourLayout, (ViewGroup) view, false);
containerDestacado.addView(inflatedLayout);

Answer 2

你可以像下面这样实现：

LayoutInflater linf;
LinearLayout rr;

linf = (LayoutInflater) getApplicationContext().getSystemService(
        Context.LAYOUT_INFLATER_SERVICE);
linf = LayoutInflater.from(activity.this);

rr = (LinearLayout) findViewById(R.id.container_destacado);

for (int i = 1; i < NoOfTimes; i++) {

    final View v = linf.inflate(R.layout.item, null);
    rr.addView(v);
}

Answer 3

在某些时候，您应该可以访问活动中的inflater，您可以使用以下代码调用它：

LayoutInflater li = LayoutInflater.from(context);

上下文是this或this.getActivity（），如果它是Fragment。然后通过以下方式充气：

View layout = li.inflate(R.layout.your_layout, null, false);

然后使用addView（布局）到container_destacado：

View containerDestacado = li.inflate(R.layout.container_destacado, null, false);
containerDestacado.addView(layout);

希望能帮助到你。

Answer 4

ll = (LinearLayout) findViewById(R.id.container_destacado);  // ll is the layout where your inflated layout will be added 
linflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int pos = 0;
    while (pos < noOfTimes) 
    {
        View myView = linflater.inflate(R.layout.item, null); //here item is the the layout you want to inflate 
        myView.setId(pos);
        /*
           You can change TextView text and ImageView images here e.g.
           TextView tv = (TextView)myView.findViewById(R.id.title_N1);
           tv.setText(pos);

        */
        pos++;
        ll.addView(myView);
    }

Answer 5

Kotlin代码这样做：

 val layoutToInflate = 
 this.layoutInflater.inflate(R.layout.ly_custom_layout, 
  null)
container_destacado.addView(layoutToInflate )

Answer 6

你有想要给其他孩子充气的LinearLayout：

LinearLayout container = (LinearLayout)parentView.findViewById(R.id.container_destacado);

使用inflater加载item.xml后，您就可以使用了

container.addView(itemView);
