My question is split into a design question and a functional question. Actual questions are in red:
*DESIGN PART OF THE QUESTION* Im trying to modify an existing project, the BluetoothLeGatt example, to turn it into ArduDroid, which is this app used to interface with Arduino via BT. The ArduDroid looks like this: <https://lh3.googleusercontent.com/-Ey0-8ov5hEE/VwWjVeipYYI/AAAAAAAAD0U/VaLd1flEUV8rqYL39F9n8JBl6NCD6JHlw/s1600/ardudroid.png> I was thinking of adding an outer table layout of 1 table and 3 rows: 1. Main layout = a Table layout with 3 rows (in dark blue) 2. First blue row: Linear layout with 2 red rows each with a seek and then a text. 3. Second blue row: Relative layout with grid layout of 4x4 green 4. Third blue row: Linear layout with 2 red rows each with a button and then a text. <https://lh3.googleusercontent.com/-mQfSiD0_FLI/VwblGZZ9oOI/AAAAAAAAD1I/E23GfHEIYp8G8lUUWdQsMXums6ByeSbPA/s1600/image%2B%25281%2529.jpeg> DESIGN QUESTION 1 So this is my xml so far, but for some reason I cant see the 2nd slider or seek component. Could someone point out why? <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"; android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:stretchColumns="1" android:divider="#000000" android:dividerPadding="@dimen/margin_medium" android:showDividers="beginning" android:visibility="visible" android:background="#fac4c4"> <!--begin my table--> <!--begin Row1 for sliders--> <TableRow android:background="#00ff00" android:layout_margin="2dip" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"; android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <!--begin Row1.row1 for Pin11--> <TableRow android:background="#00ff00" android:layout_width="match_parent" android:layout_height="match_parent"> <SeekBar android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/seekBar" android:layout_column="0"/> <TextView android:text="Pin 11" android:gravity="center" android:layout_width="match_parent" android:layout_height="match_parent" /> </TableRow> <!--begin Row1.row2 for Pin10--> <TableRow android:background="#00ff00" android:layout_width="match_parent" android:layout_height="match_parent"> <SeekBar android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/seekBar2" android:layout_column="0"/> <TextView android:text="Pin 10" android:gravity="center" android:layout_width="match_parent" android:layout_height="match_parent" /> </TableRow> </LinearLayout> </TableRow> <!--begin Row2 for buttons--> <TableRow android:background="#3676d8"> <TextView android:text="C" android:padding="3dip" /> <TextView android:text="D" android:gravity="right" android:padding="3dip" /> </TableRow> <!--begin Row3 for textfields--> <TableRow android:background="#3676d8"> <TextView android:text="E" android:padding="3dip" /> <TextView android:text="F" android:gravity="right" android:padding="3dip" /> </TableRow> </TableLayout> *FUNCTIONAL PART OF THE QUESTION* Looking at the BluetoothLEGatt example I see this structure in the layout folder to see what the main view is so that i can add my table there but I dont understand it. I have these 3 layout/*.xml files: 1. actionbar_indeterminate_progress.xml 2. gatt_services_characteristics.xml 3. listitem_devices.xml The actionbar is just a progress bar on the top left corner. The gatt_services looks to be a popup of some sort and so does the listitem xml. The project has 4 java files: 1. DeviceScanActivity.java which appears to be the default activity from the AndroidManifest. 2. DeviceControlActivity.java 3. BluetoothLEService.java which has the BT adapter and connection code 4. SampleGattAttributes.java which displays attributes of a given device. <https://lh3.googleusercontent.com/-61Tp8-WBoLA/VwaYazVfrkI/AAAAAAAAD0w/mhZlvcbak7Q3zlVicxr_aQgeN_-JoMgsA/s1600/Screenshot%2B2016-04-07%2B11.18.26.png> How do I add a new view such that it is presented after the device has been picked and connected to from the list so that I can drop my tableview layout in there? What I have done so far is add this to my DeviceScanActivity's onCreate method (just the one line added april 7): @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getActionBar().setTitle(R.string.title_devices); mHandler = new Handler(); setContentView(R.layout.activity_main); //<<<<<<<<<<< added april 7 if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) { Toast.makeText(this, R.string.ble_not_supported, Toast.LENGTH_SHORT).show(); finish(); } final BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE); mBluetoothAdapter = bluetoothManager.getAdapter(); if (mBluetoothAdapter == null) { Toast.makeText(this, R.string.error_bluetooth_not_supported, Toast.LENGTH_SHORT).show(); finish(); return; } } -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
