    <p>I have a way that I know is not the best way of sending them over rite now but I'm sending them as strings and converting them to an Int on the reciver side, the problem is when I do the conversion it crashes on my phone. This is what I have on my sender side:</p> <pre><code> public void sendMessage(View view) { // Do something in response to button Intent intent = new Intent(this, PayTracker.class); // hourly wage send EditText editText = (EditText) findViewById(R.id.hourly_wage); String message1 = editText.getText().toString(); intent.putExtra(MESSAGE_1, message1); // ot wage send EditText editText1 = (EditText) findViewById(R.id.ot_wage); String message2 = editText1.getText().toString(); intent.putExtra(MESSAGE_2, message2); // hours per day send EditText editText2 = (EditText) findViewById(R.id.hours_day); String message3 = editText2.getText().toString(); intent.putExtra(MESSAGE_3, message3); // start new activity startActivity(intent); </code></pre> <p>And this is what is on my reciving side:</p> <pre><code> @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_pay_tracker); getActionBar().setDisplayHomeAsUpEnabled(true); // Receive messages from options page Intent intent = getIntent(); String message1 = intent.getStringExtra(Options.MESSAGE_1); String message2 = intent.getStringExtra(Options.MESSAGE_2); String message3 = intent.getStringExtra(Options.MESSAGE_3); // convert string to integer int HW = Integer.valueOf(message1); int OTW = Integer.valueOf(message2); int HPD = Integer.valueOf(message3); </code></pre> <p>Ive tested everything and its the conversion that is causing the app to crash, i was hoping somebody could help me make it not crash or give me a whole new way sending an int to my second activity insted of sending a string and converting it. Thank you!</p> <p>=======================================================================</p> <p>Here is my new code with all your help!</p> <p>Sending:</p> <pre><code> public void sendMessage(View view) { // Do something in response to button Intent intent = new Intent(this, PayTracker.class); // Gather text from text boxes EditText editText = (EditText) findViewById(R.id.hourly_wage); EditText editText1 = (EditText) findViewById(R.id.ot_wage); EditText editText2 = (EditText) findViewById(R.id.hours_day); //Create String from text String message1 = editText.getText().toString(); String message2 = editText1.getText().toString(); String message3 = editText2.getText().toString(); //Convert String to Int int HW = 0, OTW = 0, HPD = 0; try{ HW = Integer.valueOf(message1); OTW = Integer.valueOf(message2); HPD = Integer.valueOf(message3); } catch(NumberFormatException nfe){ //do something else here //for e.g. initializing default values to your int variables } // Send Integers to PayTracker.java intent.putExtra(MESSAGE_HW, HW); intent.putExtra(MESSAGE_OTW, OTW); intent.putExtra(MESSAGE_HPD, HPD); // start new activity startActivity(intent); } </code></pre> <p>Receiving side:</p> <pre><code> @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_pay_tracker); getActionBar().setDisplayHomeAsUpEnabled(true); // Receive messages from options page Intent intent = getIntent(); int HW = intent.getIntExtra(Options.MESSAGE_HW, 0); int OTW = intent.getIntExtra(Options.MESSAGE_OTW, 0); int HPD = intent.getIntExtra(Options.MESSAGE_HPD, 0); // set textview TextView textView = (TextView) this.findViewById(R.id.yourpay); textView.setText(String.valueOf(HW)); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
