Question

I\'m trying to make a custom dialog, following the tutorial on the Android developer site, but it crashes every time I try to show the dialog. Here\'s my code:

Answer 1

This worked for me: problem-creating-a-custom-dialog

Use this instead of getApplicationContext() when instantiating the dialog:

Dialog dialog = new Dialog(this);

Answer 2

Consider the pattern:

private static final int MY_DIALOG= 0;

protected Dialog onCreateDialog(int id) {
    Dialog dialog;
    switch(id) {
        case MY_DIALOG:
            dialog= getInstanceMyDialog();
            break;
        default:
            dialog = null;
    }
    return dialog;
}

private Dialog getInstanceMyDialog() {
    final Dialog d= new Dialog(this); //<=====THIS
    d.setContentView(R.layout.custom_dialog);
    d.setTitle("Custom Dialog");
    return d;
}

Kotlin way to create custom dialog in android:

Dialog(activity!!, R.style.LoadingIndicatorDialogStyle)
        .apply {
            // requestWindowFeature(Window.FEATURE_NO_TITLE)
            setCancelable(true)
            setContentView(R.layout.define_your_custom_view_id_here)

            //access your custom view buttons/editText like below.z
            val createBt = findViewById<TextView>(R.id.clipboard_create_project)
            val cancelBt = findViewById<TextView>(R.id.clipboard_cancel_project)
            val clipboard_et = findViewById<TextView>(R.id.clipboard_et)
            val manualOption =
                findViewById<TextView>(R.id.clipboard_manual_add_project_option)

            //if you want to perform any operation on the button do like this

            createBt.setOnClickListener {
                //handle your button click here
                val enteredData = clipboard_et.text.toString()
                if (enteredData.isEmpty()) {
                    Utils.toast("Enter project details")
                } else {
                    navigateToAddProject(enteredData, true)
                    dismiss()
                }
            }

            cancelBt.setOnClickListener {
                dismiss()
            }
            manualOption.setOnClickListener {
                navigateToAddProject("", false)
                dismiss()
            }
            show()
        }

Create LoadingIndicatorDialogStyle in style.xml

<style name="LoadingIndicatorDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:statusBarColor">@color/black_transperant</item>
<item name="android:layout_gravity">center</item>
<item name="android:background">@android:color/transparent</item>
<!--<item name="android:windowAnimationStyle">@style/MaterialDialogSheetAnimation</item>-->
