29 * An EditorInfo describes several attributes of a text editing object
30 * that an input method is communicating with (typically an EditText), most
31 * importantly the type of text content it contains and the current cursor position.

35 * The content type of the text box, whose bits are defined by
39 * @see #TYPE_MASK_CLASS

41 * @see #TYPE_MASK_FLAGS
43 public int inputType = TYPE_NULL;
46 * Set of bits in {@link #imeOptions} that provide alternative actions
47 * associated with the "enter" key. This both helps the IME provide
48 * better feedback about what the enter key will do, and also allows it
49 * to provide alternative mechanisms for providing that command.
51 public static final int IME_MASK_ACTION = 0x000000ff;
54 * Bits of {@link #IME_MASK_ACTION}: no specific action has been
55 * associated with this editor, let the editor come up with its own if
58 public static final int IME_ACTION_UNSPECIFIED = 0x00000000;
61 * Bits of {@link #IME_MASK_ACTION}: there is no available action.
63 public static final int IME_ACTION_NONE = 0x00000001;
66 * Bits of {@link #IME_MASK_ACTION}: the action key performs a "go"
67 * operation to take the user to the target of the text they typed.
68 * Typically used, for example, when entering a URL.
70 public static final int IME_ACTION_GO = 0x00000002;
73 * Bits of {@link #IME_MASK_ACTION}: the action key performs a "search"
74 * operation, taking the user to the results of searching for the text
75 * they have typed (in whatever context is appropriate).
77 public static final int IME_ACTION_SEARCH = 0x00000003;
80 * Bits of {@link #IME_MASK_ACTION}: the action key performs a "send"
81 * operation, delivering the text to its target. This is typically used
82 * when composing a message in IM or SMS where sending is immediate.
84 public static final int IME_ACTION_SEND = 0x00000004;
87 * Bits of {@link #IME_MASK_ACTION}: the action key performs a "next"
88 * operation, taking the user to the next field that will accept text.
90 public static final int IME_ACTION_NEXT = 0x00000005;
93 * Bits of {@link #IME_MASK_ACTION}: the action key performs a "done"
94 * operation, typically meaning there is nothing more to input and the
97 public static final int IME_ACTION_DONE = 0x00000006;
100 * Bits of {@link #IME_MASK_ACTION}: like {@link #IME_ACTION_NEXT}, but
101 * for moving to the previous field. This will normally not be used to
102 * specify an action (since it precludes {@link #IME_ACTION_NEXT}), but
103 * can be returned to the app if it sets {@link #IME_FLAG_NAVIGATE_PREVIOUS}.
105 public static final int IME_ACTION_PREVIOUS = 0x00000007;
108 * Flag of {@link #imeOptions}: used to request that the IME never go
109 * into fullscreen mode.
110 * By default, IMEs may go into full screen mode when they think
111 * it's appropriate, for example on small screens in landscape
112 * orientation where displaying a software keyboard may occlude
113 * such a large portion of the screen that the remaining part is
114 * too small to meaningfully display the application UI.
115 * If this flag is set, compliant IMEs will never go into full screen mode,
116 * and always leave some space to display the application UI.
117 * Applications need to be aware that the flag is not a guarantee, and
118 * some IMEs may ignore it.
120 public static final int IME_FLAG_NO_FULLSCREEN = 0x2000000;
123 * Flag of {@link #imeOptions}: like {@link #IME_FLAG_NAVIGATE_NEXT}, but
124 * specifies there is something interesting that a backward navigation
125 * can focus on. If the user selects the IME's facility to backward
126 * navigate, this will show up in the application as an {@link #IME_ACTION_PREVIOUS}
127 * at {@link InputConnection#performEditorAction(int)
128 * InputConnection.performEditorAction(int)}.
130 public static final int IME_FLAG_NAVIGATE_PREVIOUS = 0x4000000;
133 * Flag of {@link #imeOptions}: used to specify that there is something
134 * interesting that a forward navigation can focus on. This is like using
135 * {@link #IME_ACTION_NEXT}, except allows the IME to be multiline (with
136 * an enter key) as well as provide forward navigation. Note that some
137 * IMEs may not be able to do this, especially when running on a small
138 * screen where there is little space. In that case it does not need to
139 * present a UI for this option. Like {@link #IME_ACTION_NEXT}, if the
140 * user selects the IME's facility to forward navigate, this will show up
141 * in the application at {@link InputConnection#performEditorAction(int)
142 * InputConnection.performEditorAction(int)}.
144 public static final int IME_FLAG_NAVIGATE_NEXT = 0x8000000;
147 * Flag of {@link #imeOptions}: used to specify that the IME does not need
148 * to show its extracted text UI. For input methods that may be fullscreen,
149 * often when in landscape mode, this allows them to be smaller and let part
150 * of the application be shown behind, through transparent UI parts in the
151 * fullscreen IME. The part of the UI visible to the user may not be responsive
152 * to touch because the IME will receive touch events, which may confuse the
153 * user; use {@link #IME_FLAG_NO_FULLSCREEN} instead for a better experience.
154 * Using this flag is discouraged and it may become deprecated in the future.
155 * Its meaning is unclear in some situations and it may not work appropriately
156 * on older versions of the platform.
158 public static final int IME_FLAG_NO_EXTRACT_UI = 0x10000000;
161 * Flag of {@link #imeOptions}: used in conjunction with one of the actions
162 * masked by {@link #IME_MASK_ACTION}, this indicates that the action
163 * should not be available as an accessory button on the right of the extracted
164 * text when the input method is full-screen. Note that by setting this flag,
165 * there can be cases where the action is simply never available to the
166 * user. Setting this generally means that you think that in fullscreen mode,
167 * where there is little space to show the text, it's not worth taking some
168 * screen real estate to display the action and it should be used instead
171 public static final int IME_FLAG_NO_ACCESSORY_ACTION = 0x20000000;
174 * Flag of {@link #imeOptions}: used in conjunction with one of the actions
175 * masked by {@link #IME_MASK_ACTION}. If this flag is not set, IMEs will
176 * normally replace the "enter" key with the action supplied. This flag
177 * indicates that the action should not be available in-line as a replacement
178 * for the "enter" key. Typically this is because the action has such a
179 * significant impact or is not recoverable enough that accidentally hitting
180 * it should be avoided, such as sending a message. Note that
181 * {@link android.widget.TextView} will automatically set this flag for you
182 * on multi-line text views.
184 public static final int IME_FLAG_NO_ENTER_ACTION = 0x40000000;
187 * Flag of {@link #imeOptions}: used to request an IME that is capable of
188 * inputting ASCII characters. The intention of this flag is to ensure that
189 * the user can type Roman alphabet characters in a {@link android.widget.TextView}.
190 * It is typically used for an account ID or password input. A lot of the time,
191 * IMEs are already able to input ASCII even without being told so (such IMEs
192 * already respect this flag in a sense), but there are cases when this is not
193 * the default. For instance, users of languages using a different script like
194 * Arabic, Greek, Hebrew or Russian typically have a keyboard that can't
195 * input ASCII characters by default. Applications need to be
196 * aware that the flag is not a guarantee, and some IMEs may not respect it.
197 * However, it is strongly recommended for IME authors to respect this flag
198 * especially when their IME could end up with a state where only languages
199 * using non-ASCII are enabled.

216 * private to a particular IME implementation. The string must be
217 * scoped to a package owned by the implementation, to ensure there are
218 * no conflicts between implementations, but other than that you can put
219 * whatever you want in it to communicate with the IME. For example,
220 * you could have a string that supplies an argument like
221 * <code>"com.example.myapp.SpecialMode=3"</code>. This field is can be
222 * filled in from the {@link android.R.attr#privateImeOptions}
223 * attribute of a TextView.
225 public String privateImeOptions = null;
228 * In some cases an IME may be able to display an arbitrary label for
229 * a command the user can perform, which you can specify here. This is
230 * typically used as the label for the action to use in-line as a replacement
231 * for the "enter" key (see {@link #actionId}). Remember the key where
232 * this will be displayed is typically very small, and there are significant
233 * localization challenges to make this fit in all supported languages. Also
234 * you can not count absolutely on this being used, as some IMEs may
