Question

我尝试在Android中使用EffectFactory进行一些图像处理。我试用了样品并且有效。示例：https://android.googlesource.com/platform/development/+/master/samples/HelloEffects/src/com/example/android/mediafx/HelloEffects.java

但是如何从智能手机加载图像？

问题是我这里没有ImageView，而是GLSurfaceView。

Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.puppy);

我必须使用哪种方法来获取自定义位图？

Answer 1

使用此glSurfaceView.setEGLContextClientVersion(1); glSurfaceView.setRenderer(new BitmapRenderer(getResources())); glSurfaceView.setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);类在OpenGL中绘制位图

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 
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:layout_width="match_parent"
android:layout_height="match_parent">

<WebView
    android:id="@+id/webview"
    android:layout_width="371dp"
    android:layout_height="516dp"
    tools:layout_editor_absoluteX="-12dp"
    tools:layout_editor_absoluteY="-3dp" />
   </android.support.constraint.ConstraintLayout>

将您的位图设置如下：

 <android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingTop="@dimen/appbar_padding_top"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/AppTheme.PopupOverlay">
        <TextView
            android:id="@+id/toolbar_title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="20dp"
            android:textColor="#ffffff"
            android:layout_gravity="center" />
    </android.support.v7.widget.Toolbar>
    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"></android.support.v4.view.ViewPager>

<include layout="@layout/fragment_schedule" />
