Introduction<\/a><\/h2>\n\n\n\n

BigScreenBot is a large-screen version of GreetBot, which supports large-screen display content.<\/p>\n\n\n\n

1. Permission issues<\/a><\/h2>\n\n\n\n

BigScreenBot display content must apply for the SYSTEM_ALERT_WINDOW permission of the global pop-up dialog box.<\/p>\n\n\n\n

<uses-permission android:name=\"android.permission.SYSTEM_ALERT_WINDOW\" \/><\/pre>\n\n\n\n
2. Issues with large screens<\/h2>\n\n\n\n
Due to the screen adaptation from landscape to portrait mode, the system cannot correctly read the screen information after rotation. Therefore, a coordinate transformation is implemented here to ensure the aspect ratio of the screen is correct. Please refer to the demo code for details.<\/p>\n\n\n\n
private int screenWidth = 0;\nprivate float scaleX = 0;\npublic BSImageDisplay(Context outerContext, Display display) {\n    super(outerContext, display);\n    Point pt = new Point();\n    display.getSize(pt);\n    screenWidth = pt.y * pt.y \/ pt.x;\n    scaleX = pt.x * 1.0f * pt.x \/ pt.y \/ pt.y;\n}\n@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)\n@Override\nprotected void onCreate(Bundle savedInstanceState) {\n    super.onCreate(savedInstanceState);\n    setContentView(R.layout.bs_image_layout);\n    \/\/The screen resolution requires a conversion due to the orientation (landscape or portrait) issue, hence the following conversion code is provided. Without this conversion, there would be an aspect ratio mismatch.\n    \/\/Because there is a problem, we have to rotate the screen, so we have the code below\n    findViewById(R.id.bg_image_main).getLayoutParams().width = screenWidth;\n    findViewById(R.id.bg_image_main).setScaleX(scaleX);\n   ........\n}<\/pre>\n\n\n\n
