| 83 | * <a name="ArchitectureOverview"></a> |
| 84 | * <h3>Architecture Overview</h3> |
| 85 | * |
| 86 | * <p>There are three primary parties involved in the input method |
| 87 | * framework (IMF) architecture:</p> |
| 88 | * |
| 89 | * <ul> |
| 90 | * <li> The <strong>input method manager</strong> as expressed by this class |
| 91 | * is the central point of the system that manages interaction between all |
| 92 | * other parts. It is expressed as the client-side API here which exists |
| 93 | * in each application context and communicates with a global system service |
| 94 | * that manages the interaction across all processes. |
| 95 | * <li> An <strong>input method (IME)</strong> implements a particular |
| 96 | * interaction model allowing the user to generate text. The system binds |
| 97 | * to the current input method that is use, causing it to be created and run, |
| 98 | * and tells it when to hide and show its UI. Only one IME is running at a time. |
| 99 | * <li> Multiple <strong>client applications</strong> arbitrate with the input |
| 100 | * method manager for input focus and control over the state of the IME. Only |
| 101 | * one such client is ever active (working with the IME) at a time. |
| 102 | * </ul> |
| 103 | * |
| 104 | * |
| 105 | * <a name="Applications"></a> |
| 106 | * <h3>Applications</h3> |
| 107 | * |
| 108 | * <p>In most cases, applications that are using the standard |
| 109 | * {@link android.widget.TextView} or its subclasses will have little they need |
| 110 | * to do to work well with soft input methods. The main things you need to |
| 111 | * be aware of are:</p> |
| 112 | * |
| 113 | * <ul> |
Gilles Debunne | 8cbb4c6 | 2011-01-24 12:33:56 -0800 | [diff] [blame] | 114 | * <li> Properly set the {@link android.R.attr#inputType} in your editable |
The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 115 | * text views, so that the input method will have enough context to help the |
| 116 | * user in entering text into them. |
| 117 | * <li> Deal well with losing screen space when the input method is |
| 118 | * displayed. Ideally an application should handle its window being resized |
| 119 | * smaller, but it can rely on the system performing panning of the window |
| 120 | * if needed. You should set the {@link android.R.attr#windowSoftInputMode} |
| 121 | * attribute on your activity or the corresponding values on windows you |
| 122 | * create to help the system determine whether to pan or resize (it will |
| 123 | * try to determine this automatically but may get it wrong). |
| 124 | * <li> You can also control the preferred soft input state (open, closed, etc) |
| 125 | * for your window using the same {@link android.R.attr#windowSoftInputMode} |
| 126 | * attribute. |
| 127 | * </ul> |
| 128 | * |
| 129 | * <p>More finer-grained control is available through the APIs here to directly |
| 130 | * interact with the IMF and its IME -- either showing or hiding the input |
| 131 | * area, letting the user pick an input method, etc.</p> |
| 132 | * |
| 133 | * <p>For the rare people amongst us writing their own text editors, you |
| 134 | * will need to implement {@link android.view.View#onCreateInputConnection} |
| 135 | * to return a new instance of your own {@link InputConnection} interface |
| 136 | * allowing the IME to interact with your editor.</p> |
| 137 | * |
| 138 | * |
| 139 | * <a name="InputMethods"></a> |
| 140 | * <h3>Input Methods</h3> |
| 141 | * |
| 142 | * <p>An input method (IME) is implemented |
| 143 | * as a {@link android.app.Service}, typically deriving from |
| 144 | * {@link android.inputmethodservice.InputMethodService}. It must provide |
| 145 | * the core {@link InputMethod} interface, though this is normally handled by |
| 146 | * {@link android.inputmethodservice.InputMethodService} and implementors will |
| 147 | * only need to deal with the higher-level API there.</p> |
| 148 | * |
| 149 | * See the {@link android.inputmethodservice.InputMethodService} class for |
| 150 | * more information on implementing IMEs. |
| 151 | * |
| 152 | * |
| 153 | * <a name="Security"></a> |
| 154 | * <h3>Security</h3> |
| 155 | * |
| 156 | * <p>There are a lot of security issues associated with input methods, |
| 157 | * since they essentially have freedom to completely drive the UI and monitor |
| 158 | * everything the user enters. The Android input method framework also allows |
| 159 | * arbitrary third party IMEs, so care must be taken to restrict their |
| 160 | * selection and interactions.</p> |
| 161 | * |
| 162 | * <p>Here are some key points about the security architecture behind the |
| 163 | * IMF:</p> |
| 164 | * |
| 165 | * <ul> |
| 166 | * <li> <p>Only the system is allowed to directly access an IME's |
| 167 | * {@link InputMethod} interface, via the |
| 168 | * {@link android.Manifest.permission#BIND_INPUT_METHOD} permission. This is |
| 169 | * enforced in the system by not binding to an input method service that does |
| 170 | * not require this permission, so the system can guarantee no other untrusted |
| 171 | * clients are accessing the current input method outside of its control.</p> |
| 172 | * |
| 173 | * <li> <p>There may be many client processes of the IMF, but only one may |
| 174 | * be active at a time. The inactive clients can not interact with key |
| 175 | * parts of the IMF through the mechanisms described below.</p> |
| 176 | * |
| 177 | * <li> <p>Clients of an input method are only given access to its |
| 178 | * {@link InputMethodSession} interface. One instance of this interface is |
| 179 | * created for each client, and only calls from the session associated with |
| 180 | * the active client will be processed by the current IME. This is enforced |
| 181 | * by {@link android.inputmethodservice.AbstractInputMethodService} for normal |
| 182 | * IMEs, but must be explicitly handled by an IME that is customizing the |
| 183 | * raw {@link InputMethodSession} implementation.</p> |
| 184 | * |
| 185 | * <li> <p>Only the active client's {@link InputConnection} will accept |
| 186 | * operations. The IMF tells each client process whether it is active, and |
| 187 | * the framework enforces that in inactive processes calls on to the current |
| 188 | * InputConnection will be ignored. This ensures that the current IME can |
| 189 | * only deliver events and text edits to the UI that the user sees as |
| 190 | * being in focus.</p> |
| 191 | * |
| 192 | * <li> <p>An IME can never interact with an {@link InputConnection} while |
| 193 | * the screen is off. This is enforced by making all clients inactive while |
| 194 | * the screen is off, and prevents bad IMEs from driving the UI when the user |
| 195 | * can not be aware of its behavior.</p> |
| 196 | * |
| 197 | * <li> <p>A client application can ask that the system let the user pick a |
| 198 | * new IME, but can not programmatically switch to one itself. This avoids |
| 199 | * malicious applications from switching the user to their own IME, which |
| 200 | * remains running when the user navigates away to another application. An |
| 201 | * IME, on the other hand, <em>is</em> allowed to programmatically switch |
| 202 | * the system to another IME, since it already has full control of user |
| 203 | * input.</p> |
| 204 | * |
| 205 | * <li> <p>The user must explicitly enable a new IME in settings before |
| 206 | * they can switch to it, to confirm with the system that they know about it |
| 207 | * and want to make it available for use.</p> |
| 208 | * </ul> |
