    <p>I'm designing a simple app to count the rows and stitches in crocheting/knitting, but I'm having issues. The actual counting itself is just a modified calculator: display a text field that holds the current number of stitches, and buttons which allow you to add or subtract 1, 5 or 10 to the count. Problem is, punching the buttons in the emulator doesn't work -- the thing compiles without issues and builds without issues, so I'm thinking it's something small I've (not) done.</p> <p>My Main file:</p> <pre><code>public class mainCount extends Activity { private EditText Scr; //Textbox screen private int NumberBF; //saves screen before pressing button operations private String Operation; private ButtonClickListener btnClick; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Scr = (EditText) findViewById(R.id.stitchCount); int idList[] = {R.id.stitchMin1, R.id.stitchMin5, R.id.stitchMin10, R.id.stitchPlus1, R.id.stitchPlus5, R.id.stitchPlus10, R.id.clearButton}; for(int id:idList){ View v; v = (View) findViewById(id); v.setOnClickListener(btnClick); } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main_count, menu); return true; } public void mMath(String str){ NumberBF = Integer.parseInt(Scr.getText().toString()); Operation = str; Scr.setText("0"); } private void getKeyboard(String str){ String ScrCurrent = Scr.getText().toString(); if(ScrCurrent.equals("0")) ScrCurrent = ""; ScrCurrent += str; Scr.setText(ScrCurrent); } public void mResult(String str){ int NumAf = Integer.parseInt(Scr.getText().toString()); int result = 0; if(str.equals("+1")){ result = NumAf + 1; } if(str.equals("+5")){ result = NumAf + 5; } if(str.equals("+10")){ result = NumAf + 10; } if(str.equals("-1")){ result = NumAf - 1; } if(str.equals("-5")){ result = NumAf - 5; } if(str.equals("-10")){ result = NumAf - 10; } Scr.setText(String.valueOf(result)); } // ButtonListener class private class ButtonClickListener implements View.OnClickListener{ public void onClick(View v) { switch (v.getId()) { case R.id.clearButton: //Clears stitches for this row Scr.setText("0"); NumberBF = 0; Operation = ""; break; case R.id.stitchPlus1: Operation = "+1"; mResult(Operation); break; case R.id.stitchPlus5: Operation = "+5"; mResult(Operation); break; case R.id.stitchPlus10: Operation = "+10"; mResult(Operation); break; case R.id.stitchMin1: Operation = "-1"; mResult(Operation); break; case R.id.stitchMin5: Operation = "-5"; mResult(Operation); break; case R.id.stitchMin10: Operation = "-10"; mResult(Operation); break; default: String numb = ((Button) v).getText().toString(); getKeyboard(numb); break; } } } </code></pre> <p>}</p>

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.
