Android 单击搜索图标时应用程序崩溃？
Android App crashes when clicked on the search Icon?
各位开发者大家好，
所以我开发了一个 android 应用程序来显示通过 Flickr API 公开的图像。在我将搜索功能添加到主页横幅之前，一切都很顺利。单击搜索图标时，应用程序崩溃，而不是显示带有占位符消息的下拉菜单，如下面的快照所示。
我相信错误在 FlickrRecyclerViewAdapter.java 文件
中
FlickrRecyclerViewAdapter.java 文件:

}
@Override

Log.d(LOG_TAG, " processing: " + photoItem.getmTitle() + " --> " + Integer.toString(i));
Picasso.with(mContext).load(photoItem.getmImages())

您的崩溃很可能是由于将 androidx 与旧的支持库组件混合使用造成的。将 SearchActivity 中 SearchView 的导入更改为
import androidx.appcompat.widget.SearchView;
您在 BaseActivity 中的工具栏代码也有问题。我建议使用单一方法
void activateToolbar(boolean enableHome) {
ActionBar actionBar = getSupportActionBar();
if (actionBar == null) {
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
if (toolbar != null) {
setSupportActionBar(toolbar);
actionBar = getSupportActionBar();
}
}
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(enableHome);
}
}
并根据需要传递 true 或 false。如果您随后想将其拆分为 2 个方法，请确保保留相同的功能。
您的 layout_search 不包含工具栏。您需要一个来承载搜索，因此将包含的布局从 content_search 更改为工具栏
<include android:id="@+id/app_bar" layout="@layout/toolbar"/>
最后，您在 menu_search 中多了一个菜单项。您可以从该菜单中删除 action_settings。
各位开发者大家好， 所以我开发了一个 android 应用程序来显示通过 Flickr API 公开的图像。在我将搜索功能添加到主页横幅之前，一切都很顺利。单击搜索图标时，应用程序崩溃，而不是显示带有占位符消息的下拉菜单，如下面的快照所示。 我相信错误在 FlickrRecyclerViewAdapter.java 文件

您的崩溃很可能是由于将 androidx 与旧的支持库组件混合使用造成的。将 SearchActivity 中 SearchView 的导入更改为
import androidx.appcompat.widget.SearchView;
您在 BaseActivity 中的工具栏代码也有问题。我建议使用单一方法
void activateToolbar(boolean enableHome) {
ActionBar actionBar = getSupportActionBar();
if (actionBar == null) {
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
if (toolbar != null) {
setSupportActionBar(toolbar);
actionBar = getSupportActionBar();
}
}
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(enableHome);
}
}
并根据需要传递 true 或 false。如果您随后想将其拆分为 2 个方法，请确保保留相同的功能。
您的 layout_search 不包含工具栏。您需要一个来承载搜索，因此将包含的布局从 content_search 更改为工具栏
<include android:id="@+id/app_bar" layout="@layout/toolbar"/>
最后，您在 menu_search 中多了一个菜单项。您可以从该菜单中删除 action_settings。
