回答by Adam Radomski

You could use something like

你可以使用类似的东西

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);

回答by M D

You can implement this like below:

您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);
}

回答by Kunu

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);
    }

回答by Angmar

In some point you should gain access to your inflater inside your activity, you can call it with this code:

在某些时候,您应该可以在您的活动中访问您的充气机,您可以使用以下代码调用它:

LayoutInflater li = LayoutInflater.from(context);

Where context is this or this.getActivity() if it is a Fragment. Then inflate your layour with:

如果上下文是片段,则上下文是 this 或 this.getActivity() 。然后使用以下方法膨胀您的图层:

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

Then use addView(layout) to your container_destacado:

然后使用 addView(layout) 到您的 container_destacado:

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

Hope it helps.

希望能帮助到你。

You have the LinearLayout on which you want to inflate other childs:

你有你想要膨胀其他孩子的 LinearLayout :

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

Once you loaded the item.xml with an inflater, you can just use

使用充气器加载 item.xml 后,您可以使用

container.addView(itemView);

回答by Hamed Jaliliani

Kotlin code to do so:

这样做的 Kotlin 代码:

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

Below is a working code from one of my projects:

以下是我的一个项目中的工作代码:

// The parent container
mNotificationOverlay = (LinearLayout) findViewById(R.id.container_destacado);   
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

for (Message message : m) {

    // Inflate the child layout on the fly
    final View notificationContainer = inflater.inflate(R.layout.notification_overlay_linear_layout, null);
    notificationContainer.setTag(message.getNotificationId());

    // Access children of child container
    TextView notificationOverlayTitle = (TextView) notificationContainer.findViewById(R.id.notification_title_overlay);
    TextView notificationOverlayBody = (TextView) notificationContainer.findViewById(R.id.notification_body_overlay);
    ImageButton notificationOverlayCancelButton = (ImageButton) notificationContainer.findViewById(R.id.notification_cancel_overlay);

    // Perform desired operations
    notificationOverlayCancelButton.setTag(message.getNotificationId());
    notificationOverlayTitle.setText(message.getTitle());
    notificationOverlayBody.setText(message.getNotificationBody());
    mNotificationOverlay.setVisibility(View.VISIBLE);

    // Attach any listeners
