1. CheckBox的问题
checkbox用theme设置style
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="Check Box"
android:theme="@style/MyCheckBox"/>
2.Fragment跳转和回退
//跳转
FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();
fragmentTransaction.replace(((BaseActivity) getActivity()).getFragmentContainerViewId(), fragment);
fragmentTransaction.addToBackStack(null);fragmentTransaction.commit();
//回退
@Override
public void onResume() {
super.onResume();
getView().setFocusableInTouchMode(true);
getView().requestFocus();
getView().setOnKeyListener(new View.OnKeyListener() {
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_UP && keyCode == KeyEvent.KEYCODE_BACK) {
getActivity().getSupportFragmentManager().popBackStack();
return true;
}
return false;
}
});
}
3.Fragment切换重叠问题

4. 键盘挡住输入框问题
Activity设置该属性，stateAlwaysHidden表示键盘在Activity获取焦点时隐藏.adjustResize表示软键盘弹出时，Activity的窗口大小改变。这样Activity的ScrollView不能显示完全，可以滑动。
android:windowSoftInputMode="stateAlwaysHidden|adjustResize"
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true">
<!-- Other Views -->
</ScrollView>
5. inflate的context问题
使用application使用的是application的主题，使用activity使用的是activity的主题。
6. EditText抢占焦点问题
In case the view is the first EditText it seems clearFocus() clears its focus but then starts searching for a focus candidate through the view tree and then finds out the same view. And the result is the same. But if you put android:focusableInTouchMode the focus traversal ends up on its parent.
7.DialogFragment解决重复添加问题
private void showAllowingStateLoss(@NonNull FragmentManager manager, String tag) {
final FragmentTransaction transaction = manager.beginTransaction();
transaction.remove(this);
transaction.add(this, tag);
transaction.commitAllowingStateLoss();
}
8.toolbar设置title
如果使用toolbar.setTilte，需要在setSupportActionBar之前调用才会生效。直接使用Activity的setTitle方法就可设置title。
