Example 61 with InputFilter

Example 62 with InputFilter

use of android.text.InputFilter in project CodenameOne by codenameone.

the class ResetableTextWatcher method startEditing.

/**
 * Start editing the given text-area
 * This method is executed on the UI thread, so UI manipulation is safe here.
 * @param activity Current running activity
 * @param textArea The TextAreaData instance that wraps the CN1 TextArea that our internal EditText needs to overlap.  We use
 *                 a TextAreaData so that the text area properties can be accessed off the EDT safely.
 * @param codenameOneInputType One of the input type constants in com.codename1.ui.TextArea
 * @param initialText The text that appears in the Codename One text are before the call to startEditing
 * @param isEditedFieldSwitch if true, then special case for async edit mode - the native editing is already active, no need to show
 *                            native field, just change the connected field
