I am trying to implement a HUD display to my cutsom keyboard. The HUD will contain pairs of key\/value. I need to programatically create a TableLayout and draw it on my canvas. In order to do this, I am overriding the keyboardview onDraw() method:<\/p>\n
@Override\npublic void onDraw(Canvas canvas) { \/\/ In the custom MyKeyboardView class\n MyHUD hud = new MyHUD(getContext());\n super.onDraw(canvas);\n hud.tl.draw(canvas); \/\/tl being the TableLayout to draw\n}\n<\/code><\/pre>\nMyHUD class:<\/p>\n
public class MyHUD {\n\n public TableLayout tl;\n private MyData mData;\n\n public MyHUD(Context context) {\n\n TableRow.LayoutParams trParams = new TableRow.LayoutParams(\n TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT);\n TableLayout.LayoutParams tlParams = new TableLayout.LayoutParams(\n TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT);\n\n tl = new TableLayout(context);\n tl.setLayoutParams(tlParams);\n\n for (int i = 0; i < 10; i++) {\n\n TableRow tr = new TableRow(context);\n tr.setId(100+i);\n tr.setLayoutParams(trParams);\n\n TextView charTV = new TextView(context);\n charTV.setId(200+i);\n charTV.setText(\"Hello \" + i);\n charTV.setTextColor(Color.RED);\n \/\/charTV.setLayoutParams(trParams);\n tr.addView(charTV);\n\n TextView keyTV = new TextView(context);\n keyTV.setId(300+i);\n keyTV.setText(\"world \" + i);\n keyTV.setTextColor(Color.CYAN);\n \/\/keyTV.setLayoutParams(trParams);\n tr.addView(keyTV);\n\n tl.addView(tr, tlParams); \n } \n }\n}\n<\/code><\/pre>\n(Note that currently there is no data fetching, just a “Hello world” for test purposes). I have commented out the TextView layouts, as seen on several other posts, but that doesn’t seem to be the problem.<\/p>\n
Alternative option:<\/p>\n
Instead of instanciating the TableLayout via a constructor, I have tried something like:<\/p>\n
tl = (TableLayout) findViewById(R.id.my_hud);\n<\/code><\/pre>\nAlong with the following XML:<\/p>\n
\n\n\n<\/code><\/pre>\nThe problem is that the findViewById method is undefined for my custom class.<\/p>\n
Any idea why it is not properly drawing the TableLayout?<\/p>\n","protected":false},"excerpt":{"rendered":"
