This article explains how to achieve a tab item with asymmetric rounded corners in Android Compose by either assembling three Views or drawing the shape with a Path, including detailed step‑by‑step code and a discussion of common pitfalls.
This tutorial walks through creating five typical Android dialogs—normal, list‑based, custom‑view, progress bar, and date picker—by adding buttons to a layout, writing click handlers, and using AlertDialog, ProgressDialog, and DatePickerDialog with complete code examples and screenshots.
This article explains how to apply a full‑screen grayscale effect to Android apps by using a single CSS rule for web pages and custom View subclasses—GrayImageView, GrayTextView, GrayLinearLayout, and GrayFrameLayout—plus an Activity onCreateView override to replace the root content view, complete with code snippets and practical tips.
An Android junior developer discovers a dialog‑embedded ListView that fails to scroll, investigates the custom ListViewForScrollView implementation, learns how MeasureSpec and onMeasure work, and resolves the issue by replacing the custom view with a standard ListView.
This article debunks the common belief that match_parent and wrap_content always correspond to MeasureSpec.EXACTLY and MeasureSpec.AT_MOST, explains how a parent view's spec mode and LayoutParams together determine the final MeasureSpec, and shows when UNSPECIFIED actually appears in Android layouts.
This article demonstrates how to achieve a global grayscale (black‑and‑white) effect in Android applications by adding simple CSS‑like styles for web pages and creating custom ImageView, TextView, Button, LinearLayout, FrameLayout subclasses that override draw and dispatchDraw methods, and integrating them via Activity onCreateView to replace the default content view.
