How can I disable all views inside the layout?

Question

For example I have:

Answer 1

Actully what work for me is:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE, WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

and to undo it:

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);

Answer 2

The easiest way is creating a <View in your xml, with match_parent for height and width, make sure the view is above every other views, then when you want to prevent clicks, make it visible add an onClickListener to that view with null as parameter.

Example:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
        android:layout_height="fill_parent">
     <Button 
        android:id="@+id/backbutton"
        android:text="Back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <LinearLayout
        android:id="@+id/my_layout"
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
        <TextView
            android:id="@+id/my_text_view"
            android:text="First Name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <EditText
            android:id="@+id/my_edit_view"
            android:width="100px"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" /> 
        
        <View
            android:id="@+id/disable_layout_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:visibility="gone"/>
    </LinearLayout>

</LinearLayout>

Then in your code:

val disableLayoutView = rootView.find<View>(R.id.disable_layout_view)
disableLayoutView.visibility = View.VISIBLE
disableLayoutView.setOnClickListener(null)

Details

• Android studio 3.1.4
• Kotlin 1.2.70
• checked in minSdkVersion 19

Solution

fun View.forEachChildView(closure: (View) -> Unit) {
    closure(this)
    val groupView = this as? ViewGroup ?: return
    val size = groupView.childCount - 1
    for (i in 0..size) {
        groupView.getChildAt(i).forEachChildView(closure)
    }
}

Usage

val layout = LinearLayout(context!!)
layout.forEachChildView {  it.isEnabled = false  }

val view = View(context!!)
view.forEachChildView {  it.isEnabled = false  }

val fragment = Fragment.instantiate(context, "fragment_id")
fragment.view?.forEachChildView {  it.isEnabled = false  }

My two cents function without recursion

    package io.chord.ui.utils

import android.view.View
import android.view.ViewGroup
import androidx.core.view.forEach

class ViewUtils
{
    companion object
    {
        fun setViewState(view: View, state: Boolean)
        {
            var depth = 0
            val views: MutableMap<Int, MutableList<View>> = mutableMapOf()
            views[depth] = mutableListOf(view)

            while(true)
            {
                val currentViews = views[depth]
                val nextViews = mutableListOf<View>()

                currentViews!!.forEach { view ->
                    if(view is ViewGroup)
                    {
                        view.forEach { children ->
                            nextViews.add(children)
                        }
                    }
                }

                if(nextViews.size == 0)
                {
                    break
                }

                depth++

                views[depth] = nextViews
            }

            views.flatMap {
                it.value
            }.forEach {
                it.isEnabled = state
            }
        }
    }
}

Answer 5

For me RelativeLayout or any other layout at the end of the xml file with width and height set to match_parent with attribute focusable and clickable set to true.

 <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clickable="true"
            android:focusable="true">

        <ProgressBar
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true" />

    </RelativeLayout>

Answer 6

Use below recursive function to make your child views visible or gone. First argument is your parent view and second argument decides if you want childs of parent view visible or gone. true = visible false = gone

private void layoutElemanlarininGorunumunuDegistir(View view, boolean gorunur_mu_olsun) {
    ViewGroup view_group;
    try {
        view_group = (ViewGroup) view;
        Sabitler.konsolaYazdir(TAG, "View ViewGroup imiş!" + view.getId());
    } catch (ClassCastException e) {
        Sabitler.konsolaYazdir(TAG, "View ViewGroup değilmiş!" + view.getId());
        return;
    }

    int view_eleman_sayisi = view_group.getChildCount();
    for (int i = 0; i < view_eleman_sayisi; i++) {
        View view_group_eleman = view_group.getChildAt(i);
        if (gorunur_mu_olsun) {
            view_group_eleman.setVisibility(View.VISIBLE);
        } else {
            view_group_eleman.setVisibility(View.GONE);
        }
        layoutElemanlarininGorunumunuDegistir(view_group_eleman, gorunur_mu_olsun);
    }
}
