要在Android模拟器中配置Tab键以便于更容易进行人机界面测试,可以使用以下代码示例:
ViewGroup viewGroup = findViewById(android.R.id.content);
viewGroup.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
viewGroup.setFocusableInTouchMode(true);
viewGroup.setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_TAB) {
View currentFocus = getCurrentFocus();
if (currentFocus != null) {
View nextFocus = currentFocus.focusSearch(View.FOCUS_FORWARD);
if (nextFocus != null) {
nextFocus.requestFocus();
}
}
return true;
}
return false;
}
});
这样,当在Android模拟器中运行应用程序时,按下Tab键将在人机界面中移动焦点到下一个可获得焦点的元素,使得人机界面测试更容易进行。
