Applications will not normally use this interface themselves, instead relying on the standard interaction provided by android.widget.TextView and android.widget.EditText. Those implementing input methods should normally do so by deriving from InputMethodService or one of its subclasses. When implementing...
The InputMethodSession interface provides the per-client functionality of InputMethod that is safe to expose to applications. Applications will not normally use this interface themselves, instead relying on the standard interaction provided by android.widget.TextView and android.widget.EditText....

管理每个窗口的输入事件通道(InputChannel)以及向通道上派发事件; (11)Animator 所有窗口动画的总管(WindowStateAnimator对象)。在Choreographer的驱动下,逐个渲染所有的动画; 2、Window 表示一个窗口的概念,是所有View的直接管理者,任何视图都通过Window呈现(点击事件由Window->DecorView->View;Activity的setContentView底层...
At that point, as long as the input view is visible, you will see user interaction in that view and can call back on the InputMethodService to interact with the application as appropriate. There are some situations where you want to decide whether or not your soft input view should be ...
This motivates a mode for interaction named 'touch mode'. For a touch capable device, once the user touches the screen, the device will enter touch mode. From this point onward, only views for which #isFocusableInTouchMode is true will be focusable, such as text editing widgets. Other ...
InputReader 和InputDispatcher 是跑在 SystemServer进程中的两个 native 循环线程,负责读取和分发 Input 事件。整个处理过程大致流程如下: InputReader负责从EventHub里面把Input事件读取出来,然后交给 InputDispatcher 进行事件分发; InputDispatcher在拿到 InputReader获取的事件之后,对事件进行包装后,寻找并分发到目标窗口; ...
就只有两个按钮(用于打开/关闭WIFI,扫描WIFI),一个列表(显示WIFI设备,连接WIFI)。现在xml已经有了,我们先搞定ViewBinding,修改MainActivity的代码如下所示: 代码语言:javascript 复制 publicclassMainActivityextendsAppCompatActivity{privateActivityMainBinding binding;@OverrideprotectedvoidonCreate(Bundle savedInstan...
