I have layouts which will be repetitive added in main layout:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@ id/txt_temp_feels_like"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:fontFamily="sans-serif-medium"
    android:text="-"
    android:textColor="@color/gray"
    android:textSize="18sp" />

I want it to be added to this container:

 <LinearLayout
                android:id="@ id/temp_feels_like_container"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginStart="20dp"
                android:layout_marginEnd="20dp"
                android:layout_marginBottom="20dp"
                android:orientation="horizontal">

            </LinearLayout>

And I want to do it in code. I'm using this method:

private fun setData(
            layout: List<Int>,
            container: List<ViewGroup>,
    ) {
        for (i in layout.indices) {
            container[i].addView(layoutInflater.inflate(layout[i], null))
        }
    }

where layout is link to resource of layout.

And it's fill it but i have some problems:

1. I can't set text to this added view
2. I can't set weight to this view

Maybe my algorithm is wrong. Can you help?

Could something like this help?

        <LinearLayout
        android:id="@ id/temp_feels_like_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:layout_marginEnd="20dp"
        android:layout_marginStart="20dp"
        android:orientation="horizontal"
        >

        <TextView

            android:textSize="18sp"
            />

        <TextView

            android:fontFamily="sans-serif-medium"
            android:visibility="gone"
            android:text="-"
            android:textColor="@color/gray"
            android:textSize="18sp"
            />

        <TextView
            android:id="@ id/txt_temp_feels_like4"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:fontFamily="sans-serif-medium"
            android:visibility="gone"
            android:text="-"
            android:textColor="@color/gray"
            android:textSize="18sp"
            />

    </LinearLayout>

You can have the gravity set appropriately (and the text if it's not dynamic), and then set the visibility in code rather than try to add the view.

findViewById<View>(R.id.txt_temp_feels_like1).visibility = View.VISIBLE

CodePudding user response：

It depends on when should you set the text and gravity. If you can set it before adding to layout - you can do something like that:

val view = layoutInflater.inflate(layout[i], null) as TextView
view.apply {
    text = "abc"
    params = (params as LinearLayout.LayoutParams).apply {
        weight = *value you need*
    }
}
container[i].addView(view)

Or if you need to set text to view after views are added to layout, you can reference to view via container.children/container.getChildAt(i)

UPD

you can get the child in the following way:

val count = layout.getChildCount()
var v: TextView? = null
for (i in 0..count) {
    val view = layout.getChildAt(i)
    if (view is TextView) {
        v = view
    }
}

Or one more way - set tag to view while adding it to layout and then you can get it by tag in any time you need
