    <p>Using my onEditTextchanger. It works fine when the user inputs 100000, in the EditText box it shows $100,000.00 as the user types. Which is correct. The problem is however if I try to display a numeric keyboard rather than a Qwerty keyboard. By adding in the XML I add android: inputType=”numberDecimal” I lose the formatting of $ and the, and the EditText displays like 100000.00. I have noticed this happens if I change the InputType to Number or Decimal as well. I have attached the code. Any ideas? Again Thanks in advance for your help.</p> <p>XML</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Number1" android:textAppearance="?android:attr/textAppearanceMedium" /&gt; &lt;EditText android:id="@+id/txta" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="0" /&gt; &lt;TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Number2" /&gt; &lt;EditText android:id="@+id/txtb" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="0" /&gt; &lt;TextView android:id="@+id/textView3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Number3" /&gt; &lt;TextView android:id="@+id/txtc" android:layout_width="match_parent" android:layout_height="wrap_content" /&gt; &lt;TextView android:id="@+id/textView4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Your Answer is" android:textAppearance="?android:attr/textAppearanceMedium" /&gt; &lt;TextView android:id="@+id/txtd" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; &lt;Button android:id="@+id/buttonCalc" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Calculate" /&gt; </code></pre> <p></p> <p>Java</p> <pre><code>public class CalcTestActivity extends Activity { private EditText txta; private EditText txtb; private TextView txtc; private TextView txtd; private double a = 0; private double b = 0; private double c = 0; private double d = 0; private Button buttonCalc; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initControls(); txta.addTextChangedListener(new CurrencyTextWatcher()); txtb.addTextChangedListener(new CurrencyTextWatcher()); } private void initControls() { txta = (EditText)findViewById(R.id.txta); txtb = (EditText)findViewById(R.id.txtb); txtc = (TextView)findViewById(R.id.txtc); txtd = (TextView)findViewById(R.id.txtd); buttonCalc = (Button)findViewById(R.id.buttonCalc); buttonCalc.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) {calculate(); }});} private void calculate() { a=Double.parseDouble(txta.getText().toString().replace("$", "").replace(",", "")); b=Double.parseDouble(txtb.getText().toString().replace("$", "").replace(",", "")); c=Math.round(a*.88); txtc.setText(GlobalMoney.FormatValue(c)); d=Math.round((a*.87)+(b*.61)*(c*.25)); txtd.setText(GlobalMoney.FormatValue(d)); } } </code></pre> <p>TextWatcher</p> <pre><code>import java.text.NumberFormat; import android.text.Editable; import android.text.TextWatcher; public class CurrencyTextWatcher implements TextWatcher { boolean mEditing; public CurrencyTextWatcher() { mEditing = false; } public void afterTextChanged(Editable s) { // TODO Auto-generated method stub if(!mEditing) { mEditing = true; String digits = s.toString().replaceAll("\\D", ""); NumberFormat nf = NumberFormat.getCurrencyInstance(); try{ String formatted = nf.format(Double.parseDouble(digits)/100); s.replace(0, s.length(), formatted); } catch (NumberFormatException nfe) { s.clear(); } mEditing = false; } } public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } } </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.
