In this post, we will learn to create a custom AlertDialog without using any library. This will help us to the theme and customize our app and make it more user-friendly.
Below is the design that we are going to create.
We are going to create a layout file called dialog_daily_check.xml. This will be the layout of our dialog.
Then, we will create drawables for our dialog background which will be applied on the layouts.
First one is dialog_main_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="https://schemas.android.com/apk/res/android" >
<solid android:color="#FFCC80" />
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>Second one is dialog_accent.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="https://schemas.android.com/apk/res/android" >
<solid android:color="#E65100" />
<corners
android:topLeftRadius="12dp"
android:topRightRadius="12dp" />
</shape>After that, we will edit the layout of our dialog.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="https://schemas.android.com/apk/res/android"

</androidx.cardview.widget.CardView>
</FrameLayout>
</FrameLayout>Note: we are using cardview to create rounded buttons and a library to create rounded images which is completely optional.
Now let’s create our java file. Create a java file called DailyCheckDialog.java
package com.connectmymatch.mash.ui.dialogs;
import android.app.Dialog;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.DialogFragment;
import androidx.appcompat.app.AlertDialog;
import androidx.cardview.widget.CardView;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import com.connectmymatch.mash.R;
public class DailyCheckDialog extends DialogFragment {
CardView cancelBtn, checkInBtn, coinsBtn;
View view;
Dialog d;
AlertDialog.Builder builder;
LinearLayout dialogMain;
FrameLayout mainTop;
@NonNull
@Override
public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {
builder = new AlertDialog.Builder(getActivity());
view = LayoutInflater.from(getContext()).inflate(R.layout.dialog_daily_check, null);
cancelBtn = view.findViewById(R.id.cancel_btn);
checkInBtn = view.findViewById(R.id.check_in_btn);
coinsBtn = view.findViewById(R.id.coinx2);
dialogMain = view.findViewById(R.id.main_dialog);
mainTop = view.findViewById(R.id.main_top);
mainTop.setVisibility(View.VISIBLE);
dialogMain.setVisibility(View.VISIBLE);
builder.setView(view);
d = builder.create();
d.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
coinsBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
cancelBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
checkInBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(getContext(), DialogCheckinActivity.class);
startActivity(i);
d.dismiss();
}
});
return d;
}
}
Now, to launch the dialog, we call these lines:
FragmentManager fm = getSupportFragmentManager(); DailyCheckDialog alertDialog = new DailyCheckDialog(); alertDialog.show(fm, "fragment_alert");
Our custom dialog will be displayed.
