| 81 | * InputMethodService provides a standard implementation of an InputMethod, |
| 82 | * which final implementations can derive from and customize. See the |
| 83 | * base class {@link AbstractInputMethodService} and the {@link InputMethod} |
| 84 | * interface for more information on the basics of writing input methods. |
| 85 | * |
| 86 | * <p>In addition to the normal Service lifecycle methods, this class |
| 87 | * introduces some new specific callbacks that most subclasses will want |
| 88 | * to make use of:</p> |
| 89 | * <ul> |
| 90 | * <li> {@link #onInitializeInterface()} for user-interface initialization, |
| 91 | * in particular to deal with configuration changes while the service is |
| 92 | * running. |
| 93 | * <li> {@link #onBindInput} to find out about switching to a new client. |
| 94 | * <li> {@link #onStartInput} to deal with an input session starting with |
| 95 | * the client. |
| 96 | * <li> {@link #onCreateInputView()}, {@link #onCreateCandidatesView()}, |
| 97 | * and {@link #onCreateExtractTextView()} for non-demand generation of the UI. |
| 98 | * <li> {@link #onStartInputView(EditorInfo, boolean)} to deal with input |
| 99 | * starting within the input area of the IME. |
| 100 | * </ul> |
| 101 | * |
| 102 | * <p>An input method has significant discretion in how it goes about its |
| 103 | * work: the {@link android.inputmethodservice.InputMethodService} provides |
| 104 | * a basic framework for standard UI elements (input view, candidates view, |
| 105 | * and running in fullscreen mode), but it is up to a particular implementor |
| 106 | * to decide how to use them. For example, one input method could implement |
| 107 | * an input area with a keyboard, another could allow the user to draw text, |
| 108 | * while a third could have no input area (and thus not be visible to the |
| 109 | * user) but instead listen to audio and perform text to speech conversion.</p> |
| 110 | * |
| 111 | * <p>In the implementation provided here, all of these elements are placed |
| 112 | * together in a single window managed by the InputMethodService. It will |
| 113 | * execute callbacks as it needs information about them, and provides APIs for |
| 114 | * programmatic control over them. They layout of these elements is explicitly |
| 115 | * defined:</p> |
| 116 | * |
| 117 | * <ul> |
| 118 | * <li>The soft input view, if available, is placed at the bottom of the |
| 119 | * screen. |
| 120 | * <li>The candidates view, if currently shown, is placed above the soft |
| 121 | * input view. |
| 122 | * <li>If not running fullscreen, the application is moved or resized to be |
| 123 | * above these views; if running fullscreen, the window will completely cover |
| 124 | * the application and its top part will contain the extract text of what is |
| 125 | * currently being edited by the application. |
| 126 | * </ul> |
| 127 | * |
| 128 | * |
| 129 | * <a name="SoftInputView"></a> |
| 130 | * <h3>Soft Input View</h3> |
| 131 | * |
| 132 | * <p>Central to most input methods is the soft input view. This is where most |
| 133 | * user interaction occurs: pressing on soft keys, drawing characters, or |
| 134 | * however else your input method wants to generate text. Most implementations |
| 135 | * will simply have their own view doing all of this work, and return a new |
| 136 | * instance of it when {@link #onCreateInputView()} is called. At that point, |
| 137 | * as long as the input view is visible, you will see user interaction in |
| 138 | * that view and can call back on the InputMethodService to interact with the |
| 139 | * application as appropriate.</p> |
| 140 | * |
| 141 | * <p>There are some situations where you want to decide whether or not your |
| 142 | * soft input view should be shown to the user. This is done by implementing |
| 143 | * the {@link #onEvaluateInputViewShown()} to return true or false based on |
| 144 | * whether it should be shown in the current environment. If any of your |
| 145 | * state has changed that may impact this, call |
| 146 | * {@link #updateInputViewShown()} to have it re-evaluated. The default |
| 147 | * implementation always shows the input view unless there is a hard |
| 148 | * keyboard available, which is the appropriate behavior for most input |
| 149 | * methods.</p> |
| 150 | * |
| 151 | * |
| 152 | * <a name="CandidatesView"></a> |
| 153 | * <h3>Candidates View</h3> |
| 154 | * |
| 155 | * <p>Often while the user is generating raw text, an input method wants to |
| 156 | * provide them with a list of possible interpretations of that text that can |
| 157 | * be selected for use. This is accomplished with the candidates view, and |
| 158 | * like the soft input view you implement {@link #onCreateCandidatesView()} |
| 159 | * to instantiate your own view implementing your candidates UI.</p> |
| 160 | * |
| 161 | * <p>Management of the candidates view is a little different than the input |
| 162 | * view, because the candidates view tends to be more transient, being shown |
| 163 | * only when there are possible candidates for the current text being entered |
| 164 | * by the user. To control whether the candidates view is shown, you use |
| 165 | * {@link #setCandidatesViewShown(boolean)}. Note that because the candidate |
| 166 | * view tends to be shown and hidden a lot, it does not impact the application |
| 167 | * UI in the same way as the soft input view: it will never cause application |
| 168 | * windows to resize, only cause them to be panned if needed for the user to |
| 169 | * see the current focus.</p> |
| 170 | * |
| 171 | * |
| 172 | * <a name="FullscreenMode"></a> |
| 173 | * <h3>Fullscreen Mode</h3> |
| 174 | * |
| 175 | * <p>Sometimes your input method UI is too large to integrate with the |
| 176 | * application UI, so you just want to take over the screen. This is |
| 177 | * accomplished by switching to full-screen mode, causing the input method |
| 178 | * window to fill the entire screen and add its own "extracted text" editor |
| 179 | * showing the user the text that is being typed. Unlike the other UI elements, |
| 180 | * there is a standard implementation for the extract editor that you should |
| 181 | * not need to change. The editor is placed at the top of the IME, above the |
| 182 | * input and candidates views.</p> |
| 183 | * |
| 184 | * <p>Similar to the input view, you control whether the IME is running in |
| 185 | * fullscreen mode by implementing {@link #onEvaluateFullscreenMode()} |
| 186 | * to return true or false based on |
| 187 | * whether it should be fullscreen in the current environment. If any of your |
| 188 | * state has changed that may impact this, call |
| 189 | * {@link #updateFullscreenMode()} to have it re-evaluated. The default |
| 190 | * implementation selects fullscreen mode when the screen is in a landscape |
| 191 | * orientation, which is appropriate behavior for most input methods that have |
| 192 | * a significant input area.</p> |
| 193 | * |
| 194 | * <p>When in fullscreen mode, you have some special requirements because the |
| 195 | * user can not see the application UI. In particular, you should implement |
| 196 | * {@link #onDisplayCompletions(CompletionInfo[])} to show completions |
| 197 | * generated by your application, typically in your candidates view like you |
| 198 | * would normally show candidates. |
| 199 | * |
| 200 | * |
| 201 | * <a name="GeneratingText"></a> |
| 202 | * <h3>Generating Text</h3> |
| 203 | * |
| 204 | * <p>The key part of an IME is of course generating text for the application. |
| 205 | * This is done through calls to the |
| 206 | * {@link android.view.inputmethod.InputConnection} interface to the |
| 207 | * application, which can be retrieved from {@link #getCurrentInputConnection()}. |
| 208 | * This interface allows you to generate raw key events or, if the target |
| 209 | * supports it, directly edit in strings of candidates and committed text.</p> |
| 210 | * |
| 211 | * <p>Information about what the target is expected and supports can be found |
| 212 | * through the {@link android.view.inputmethod.EditorInfo} class, which is |
| 213 | * retrieved with {@link #getCurrentInputEditorInfo()} method. The most |
| 214 | * important part of this is {@link android.view.inputmethod.EditorInfo#inputType |
| 215 | * EditorInfo.inputType}; in particular, if this is |
| 216 | * {@link android.view.inputmethod.EditorInfo#TYPE_NULL EditorInfo.TYPE_NULL}, |
| 217 | * then the target does not support complex edits and you need to only deliver |
| 218 | * raw key events to it. An input method will also want to look at other |
| 219 | * values here, to for example detect password mode, auto complete text views, |
| 220 | * phone number entry, etc.</p> |
| 221 | * |
| 222 | * <p>When the user switches between input targets, you will receive calls to |
| 223 | * {@link #onFinishInput()} and {@link #onStartInput(EditorInfo, boolean)}. |
| 224 | * You can use these to reset and initialize your input state for the current |
| 225 | * target. For example, you will often want to clear any input state, and |
| 226 | * update a soft keyboard to be appropriate for the new inputType.</p> |
