Step 1: Installation

Adding the depencency

Add this to your root build.gradle file:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Now add the dependency to your app build.gradle file:

implementation 'com.github.marcoscgdev:HeaderDialog:1.0.6'

Step 2: Creating the dialog

Here is a complete snippet of it usage:

new HeaderDialog(this)
    .setColor(getResources().getColor(R.color.colorAccent)) // Sets the header background color
    .setElevation(false) // Sets the header elevation, true by default
    .setIcon(getResources().getDrawable(R.drawable.ic_info_outline_black_48dp)) // Sets the dialog icon image
    .setTitle(getResources().getString(R.string.library_name)) // Sets the dialog title
    .setMessage("Lorem ipsum dolor sit amet...") // Sets the dialog message
    .justifyContent(true) // Justifies the message text, false by default
    .setTitleColor(Color.parseColor("#212121")) // Sets the header title text color
    .setIconColor(Color.parseColor("#212121")) // Sets the header icon color
    .setTitleGravity(Gravity.CENTER_HORIZONTAL) // Sets the header title text gravity
    .setMessageGravity(Gravity.CENTER_HORIZONTAL) // Sets the message text gravity
    .setTitleMultiline(false) // Multiline header title text option, true by default
    .setView(R.layout.custom); // Set custom view to the dialog (only possible via layout resource)
    .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
    // Your action
        }
    })
    .setNegativeButton("Close", null)
    .show();

Important note: Do not enable the justified text if you are using html content!

Step 3: Accessing inflated custom view

HeaderDialog headerDialog = new HeaderDialog(this);
...
headerDialog.show();
headerDialog.getInflatedView().findViewById(R.id.checkbox).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Toast.makeText(MainActivity.this, "Checkbox clicked!", Toast.LENGTH_SHORT).show();
    }
});
