我一直在玩 Google 的新设计支持库,真是太棒了!我只是在导航视图上有点难过。我读到的所有东西都说它NavigationView
足够聪明,可以自己处理透明的稀松布。(android-developers发布,其中之一;搜索 scrim)。无论如何,当我尝试这样做时,我得到以下结果:
这很棒;正是我想要的。除了一件事。当抽屉关闭时,稀松布是难看的深灰色,而不是我的 primaryColorDark 。. .
这是我的布局:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true" >
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:id="@+id/linear_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="@layout/toolbar" />
<fragment
android:id="@+id/fragment"
android:name="com.gmail.rixx.justin.envelopebudget.HomeFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout="@layout/fragment_home" />
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="@dimen/fab_margin"
app:backgroundTint="@color/accent"
android:src="@drawable/ic_add_white_24dp" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/drawer" />
</android.support.v4.widget.DrawerLayout>
活动代码:
public class Home extends ActionBarActivity {
private Toolbar mToolbar;
private DrawerLayout mDrawerLayout;
private Context mContext = this;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
setUpToolbar();
setUpNavDrawer();
findViewById(R.id.fab).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(mContext, NewTransactionActivity.class));
}
});
}
private void setUpToolbar() {
mToolbar = (Toolbar) findViewById(R.id.toolbar);
if (mToolbar != null) {
setSupportActionBar(mToolbar);
}
}
private void setUpNavDrawer() {
if (mToolbar != null) {
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mToolbar.setNavigationIcon(R.drawable.ic_menu_white_24dp);
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
mDrawerLayout.openDrawer(GravityCompat.START);
}
});
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_home, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
和 v21/样式:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="AppTheme.Base">
<item name="android:colorPrimary">@color/primary</item>
<item name="android:colorPrimaryDark">@color/primary_dark</item>
<item name="android:colorAccent">@color/accent</item>
<item name="android:textColorPrimary">@color/primary_text</item>
<item name="android:textColorSecondary">@color/secondary_text</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
</resources>
我在github上模仿 Chris Banes 的 CheeseSquare 应用程序,但我没有得到我想要的行为。
我试过从 v21/styles 中删除windowDrawsSystemBarBackgrounds
and statusBarColor
,我得到了正确的颜色,但状态栏永远不会透明:
帮助将不胜感激。这是新东西,所以我知道我们都在学习。
谢谢阅读!
