我想使用 NavigationView 设置 navigation drawer。项目是不可见的，但是当我们点击空白区域时，特定的项目点击代码就会被执行。看起来项目是不可见的但可以点击。

我试过使用背景颜色，但似乎不起作用。

如有任何帮助，我们将不胜感激。

自定义 TextView

public class CustomTextView extends TextView {

public CustomTextView(Context context) {
    super(context);
    // TODO Auto-generated constructor stub

    if (!isInEditMode())
        setCustomFont(context);
}

public CustomTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    // TODO Auto-generated constructor stub

    if (!isInEditMode())
        setCustomFont(context);
}

public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    // TODO Auto-generated constructor stub

    if (!isInEditMode())
        setCustomFont(context);
}

public void setCustomFont(Context ctx) {

    Typeface tf = Typeface.createFromAsset(ctx.getAssets(),
            "fonts/DroidSerif_Regular.ttf");

    setTypeface(tf);

  }
 }

主题

 <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">

    <item name="colorPrimary">@color/Black</item>
    <item name="android:textColorPrimary">@color/Black</item>
    <item name="android:textColorSecondary">@color/Black</item>
    <item name="colorAccent">@color/Orange</item>
    <item name="textColor">@color/Black</item>
</style>

最佳答案

终于!!我让它工作了。

在 navigation_header 根布局高度应该是 wrap_content 而不是 match_parent

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" // This should be wrap_content
android:background="@color/White">

<LinearLayout
android:id="@+id/navigationHeader"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/accent_material_dark"
android:orientation="vertical">

<ImageView
    android:id="@+id/ivDrawerIcon"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_marginTop="20dp"
    android:layout_gravity="center_horizontal"
    android:src="@drawable/orion_elite_logo" />

<com.squawkinit.orionfreightelite.customview.CustomTextView
    android:id="@+id/tvDrawerName"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:textColor="@color/White"
    android:textSize="16sp" />

<com.squawkinit.orionfreightelite.customview.CustomTextView
    android:id="@+id/tvDrawerMobile"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginBottom="5dp"
    android:textColor="@color/LightWhite"
    android:textSize="14sp" />

关于android - NavigationView 不可见，但项目点击有效，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40447234/
