当我在textview或imageview中使用VectorDrawable资源时,使用"android:DrawableRight"/"android:DrawableEnd"/"android:DrawableStart"/"android:DrawableLeft"时会出现运行时崩溃.

该应用程序将编译正常,没有任何警告.

我在用

• Gradle 1.5
• 支持库23.2('com.android.support:appcompat-v7:23.2.0')

我发现的是,我可以通过编程方式在Java中分配SVG,而不会像这样崩溃.

TextView tv = (TextView) findViewById(R.id.textView);
tv.setCompoundDrawablesWithIntrinsicBounds(null,null, getResources().getDrawable(R.drawable.ic_accessible_white_36px),null);

(我怀疑这是23.2的支持库错误.)

但是可以将drawableRight等用于SVG资产吗？

这是我的布局

<?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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="au.com.angryitguy.testsvg.MainActivity">


<TextView
    android:id="@+id/textView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:drawableRight="@drawable/ic_accessible_white_36px"
    android:background="@color/colorPrimary"
    android:textColor="#FFFFFF"
    android:textSize="22sp"
    android:text="Hello World!"/>
</RelativeLayout>

这是我的活动

package au.com.angryitguy.testsvg;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        }
    }

以下是Google材料设计网站中未经修改的VectorDrawable资产.

我正在开发一个Android项目,我选择<vector>显示图标,因为它具有适应性和动态性,但是,我只能在运行Android的设备上运行此应用程序,该设备具有API 21或更高版本.我的问题是如何<vector>在较低的Android版本即API 14或类型上使用.谢谢!

通过使用Android新Android应用程序包我发现我的2个谷歌游戏商店应用程序中找不到资源崩溃: -

这是应用程序之一的面料堆栈跟踪: -

当我启用

vectorDrawables.useSupportLibrary = true

我在KitKat和以下设备上获得了很多resourceNotFoundExceptions.我得到了这个用于NavigationView for Menus以及用于带有app:srcCompat的ImageViews

用于NavigationView

java.lang.RuntimeException: Unable to start activity ComponentInfo{org.ligi.gobandroid_hd/org.ligi.gobandroid_hd.ui.game_setup.GoSetupActivity}: android.view.InflateException: …

我看到一些设备在野外间歇性崩溃，其中Android报告FileNotFoundException夸大了资源文件。最初，这只是Android SDK提供的资源：

    res/interpolator/linear_out_slow_in.xml
    res/color/highlighted_text_material.xml

但是现在我的文件崩溃了：

    res/layout/listitem_spinner_text.xml

我发现其他一些文章提到了minifyEnabled和rinkleResources，但是我的应用程序未启用这些功能。（特别是，minifyEnabled设置为false，而gradle文件中未包含rinkleResources。）突出的一件事是，我仅在Pixel Devices上看到了崩溃，我相信它都是OS 7+版本。
我怀疑是否会排除xml文件，因为我无法在模拟器上的任何设备或Pixel上重现崩溃。

是什么原因导致此崩溃？

我的应用程序当前使用buildToolsVersion 25.0.2和gradle 2.2.3构建，我想我的下一步可能是尝试在一个云场中的真实设备上重现吗？

这是崩溃之一：

更新：由于无法轻松访问Pixel或Android 7设备，因此我花了一些时间使用带有7.1.1的自定义ROM升级Nexus 5。该应用程序即使在分屏模式下也可以在此设备上正常运行，因此我仍然不知道为什么某些设备报告此错误。

我有一个带有渐变组件的图标。

我创建了一个带有图像图标的自定义视图，并像这样初始化它：

XML

IconFieldLinearLayout.java

private void initAttr(Context context, AttributeSet attrs) {

        if (attrs != null) {
            TypedArray a = context.obtainStyledAttributes(attrs,
                    R.styleable.IconFieldLinearLayout, 0, 0);



            Drawable icon = a.getDrawable(R.styleable.IconFieldLinearLayout_icon);
            boolean tintIcon = a.getBoolean(R.styleable.IconFieldLinearLayout_tintIcon, true);
            int color = a.getColor(R.styleable.IconFieldLinearLayout_tintColor, Color.WHITE);

            a.recycle();
            initIcon(context, icon, tintIcon, color);
        } else {
            initIcon(context, mDefaultDrawable, true, Color.WHITE);
        }
    }

当我使用这个 drawable 在 Android 4.3 上运行它时：

        android:width="24dp"
        android:height="24dp"

您可能见过 Gmail 等应用程序的侧面导航抽屉。但是如何使用自定义小部件制作这样一个抽屉，例如我展示了一个导航抽屉，其中随机放置了一些小部件：

我想使用constraintLayout导航视图内部。基本上，我希望它是一个正常的布局/视图，占据一定比例的屏幕并具有滑入和滑出动画。

编辑

如果你不添加app:menu=@menu/menu_nav，那么它基本上会崩溃，如果你添加一个空白菜单，那么你不能只将constraintLayout放在导航菜单中，你必须将constraintLayout放在FrameLayout中......最后它没有无法正常工作，假设您在 imageView 中使用匹配约束，则图像不会显示，尽管硬编码字符串目前可以，但这并不能真正解决视图动态的问题。
