| 27 | * <p>This class encapsulates a completion offered by an application |
| 28 | * that wants it to be presented to the user by the IME. Usually, apps |
| 29 | * present their completions directly in a scrolling list for example |
| 30 | * (UI developers will usually use or extend |
| 31 | * {@see android.widget.AutoCompleteTextView} to implement this). |
| 32 | * However, in some cases, the editor may not be visible, as in the |
| 33 | * case in extract mode where the IME has taken over the full |
| 34 | * screen. In this case, the editor can choose to send their |
| 35 | * completions to the IME for display. |
| 36 | * |
| 37 | * <p>Most applications who want to send completions to an IME should use |
| 38 | * {@link android.widget.AutoCompleteTextView} as this class makes this |
| 39 | * process easy. In this case, the application would not have to deal directly |
| 40 | * with this class. |
| 41 | * |
| 42 | * <p>An application who implements its own editor and wants direct control |
| 43 | * over this would create an array of CompletionInfo objects, and send it to the IME using |
| 44 | * {@link InputMethodManager#displayCompletions(View, CompletionInfo[])}. |
| 45 | * The IME would present the completions however they see fit, and |
| 46 | * call back to the editor through |
| 47 | * {@link InputConnection#commitCompletion(CompletionInfo)}. |
| 48 | * The application can then pick up the commit event by overriding |
| 49 | * {@link android.widget.TextView#onCommitCompletion(CompletionInfo)}. |
