作为标题,我的PreferenceFragment与我的工具栏重叠。我已经尝试过不同的解决方案,但问题仍然存在。希望在任何帮助。这是我的代码。
的活动:
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class MyActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
// Display the fragment as the main content
getFragmentManager().beginTransaction().replace(android.R.id.content, new SettingsFragment()).commit();
}
}
活动XML(activity_settings.xml):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.mypackage.MyActivity">
<include
layout="@layout/app_bar" />
<FrameLayout
android:id="@+id/pref_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/app_bar"/>
</RelativeLayout>
Fragment(SettingsFragment.java):
import android.preference.PreferenceFragment;
import android.os.Bundle;
public class SettingsFragment extends PreferenceFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.pref_settings);
}
}
片段XML(pref_settings.xml):
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference
android:key="pref_checkbox"
android:title="Title"
android:summary="Summary"
android:defaultValue="false"/>
</PreferenceScreen>
工具栏(app_bar.xml):
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/app_bar"
android:background="@color/primaryColor"
android:elevation="3dp"
app:theme="@style/ThemeOverlay.AppCompat.Dark" />

改变这个:
getFragmentManager().beginTransaction().replace(android.R.id.content, new SettingsFragment()).commit();
为:
getFragmentManager().beginTransaction().replace(R.id.pref_content, new SettingsFragment()).commit();

我也遇到过类似的问题。我通过在onCreateView()
方法中向视图添加填充来解决它。这article也帮助我解决了我的问题。
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = super.onCreateView(inflater, container, savedInstanceState);
// calculate margins
int horizontalMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 2, getResources().getDisplayMetrics());
int verticalMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 2, getResources().getDisplayMetrics());
int topMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, (int) getResources().getDimension(R.dimen.activity_vertical_margin) + 30, getResources().getDisplayMetrics());
view.setPadding(horizontalMargin, topMargin, horizontalMargin, verticalMargin);
return view;
}
答案 2 :(得分:0)
我最终通过替换Activity XML
来解决了这个问题:
<include
layout="@layout/app_bar" />
使用新工具栏:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/app_bar_settings"
android:background="@color/primaryColor"
android:elevation="3dp"
android:theme="@style/ThemeOverlay.AppCompat.Dark" />
