我在MainActivity
中有工具栏。这是我要在工具栏内设置标题,图像和后退按钮的片段。在这里,我正在使用底部导航来更改片段。我想为每个片段设置不同的标题和图像。我必须将标题设置为工具栏的中心,并将后退按钮设置为工具栏的右上角。
答案 0 :(得分:0)
在您的MainActivity中,将这些行添加到OnCreate()方法中
if (getSupportActionBar() != null) {
getSupportActionBar().setTitle("My Activity Title");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
要使用后退箭头,您可以在onCreate()之外编写此代码
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
Toast.makeText(this, "Back button pressed", Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
在片段中,您可以更改工具栏的标题
getActivity().setTitle("My fragment Title");
答案 1 :(得分:0)
您可以使用箭头ImageView
和TextView
创建自定义工具栏。
include_tool_bar.xml
<com.mastercard.wallet.ui.widget.CustomTextView
android:id="@+id/toolbar_title"
style="@style/Toolbar.TitleText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical|left"
android:textSize="@dimen/px_48"
app:fontName="InterStateLight"
customviews:fontName="InterStateLight" />
<ImageView
android:id="@+id/toolbar_logo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:contentDescription="@string/adaCitiPayLogoText"
android:src="@drawable/ab_logo"
android:visibility="gone" />
并添加工具栏
Toolbar toolbar = (Toolbar) appCompatActivity.findViewById(R.id.toolbar);
ImageView logo = (ImageView) toolbar.findViewById(R.id.toolbar_logo);
CustomTextView textView = (CustomTextView) toolbar.findViewById(R.id.toolbar_title);
logo.setVisibility(View.VISIBLE);
logo.setImageResource(logoResourceId);
textView.setVisibility(View.GONE);
appCompatActivity.setSupportActionBar(toolbar);
appCompatActivity.getSupportActionBar().setDisplayShowTitleEnabled(false);
答案 2 :(得分:0)
标题从片段更改为 onActivityCreated
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
((MainActivity) getActivity()).getSupportActionBar().setTitle(getString(R.string.menu_about_us));
((MainActivity) getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((MainActivity) getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);
}
在您的活动中,确保添加这样的工具栏。
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="@color/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay"/>
并将其设置为您的活动
setSupportActionBar(findViewById(R.id.toolbar));
对于后按,只需添加一个侦听器并执行需要的操作即可。
toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_action_back));
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// pop up fragment or take another action
}
});
