EditText with number keypad by default, but allowing alphabetic characters

Define your EditText in your xml this way:

<EditText     android:id="@+id/txtOppCodigoCliente"    android:inputType="textVisiblePassword"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:maxLength="11"    android:hint="@string/strCodigoCliente"/>

output: android:inputType="textVisiblePassword"

A row of numbers and the rest of letters.

I would suggest a more Robust solution:

Present the user with the ability to choose the input type:

NEEDED FIXES

-better handling of showing/hiding the input selection buttons

-probably remove the suggestions when the input type is letter

Here is the activity:

package mobi.sherif.numberstexttextview;import android.os.Bundle;import android.app.Activity;import android.text.InputType;import android.view.View;import android.view.View.OnFocusChangeListener;import android.widget.EditText;public class MainActivity extends Activity {    EditText mEdit;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mEdit = (EditText) findViewById(R.id.input);        mEdit.setOnFocusChangeListener(new OnFocusChangeListener() {            @Override            public void onFocusChange(View view, boolean focused) {                findViewById(R.id.llmenu).setVisibility(focused?View.VISIBLE:View.GONE);            }        });    }    public void onNumbers(View v) {        mEdit.setInputType(InputType.TYPE_CLASS_NUMBER);    }    public void onLetters(View v) {        mEdit.setInputType(InputType.TYPE_CLASS_TEXT);    }}

Here is the activity's xml : activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <ScrollView        android:id="@+id/scrollview"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:layout_alignWithParentIfMissing="true"        android:layout_above="@+id/llmenu" >        <LinearLayout            android:layout_width="match_parent"            android:layout_height="wrap_content" >            <EditText                android:id="@+id/input"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:inputType="number" >                <requestFocus />            </EditText>        </LinearLayout>    </ScrollView>    <LinearLayout        android:id="@+id/llmenu"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:background="#000000"        android:padding="0dp" >        <Button            android:id="@+id/buttonnumbers"            android:layout_width="0dp"            android:onClick="onNumbers"            android:layout_height="match_parent"            android:layout_weight="1"            android:text="Numbers" />        <Button            android:id="@+id/buttonletters"            android:layout_width="0dp"            android:layout_height="match_parent"            android:layout_weight="1"            android:onClick="onLetters"            android:text="Letters" />    </LinearLayout></RelativeLayout>

Here is what you are looking for:

Define your EditText in your xml this way:

<EditText    android:id="@+id/etTest"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:ems="10"    android:hint="@string/hint"></EditText>

And call following in your onCreate():

etTest = (EditText) findViewById(R.id.etTest);etTest.setRawInputType(InputType.TYPE_CLASS_NUMBER);// Note the "Raw"

Whenever you click into your EditText now, you can enter digits AND letters! (Digit keyboard is shown first)
