安卓:编程创建的图像VS资源图片 [英] Android: programmatically created image vs resource image
问题描述
1)是否有可能创造绘,例如
1) Is it possible to create drawable, example
static Bitmap.Config conf = Bitmap.Config.ARGB_8888;
static Bitmap bmp = Bitmap.createBitmap(100, 100, conf);
// something draw
// eventually convert to DrawableBitmap
然后将其转换/ asiggn为/投放资源,在功能使用具有资源ID参数,如:
and then convert it / asiggn as / put in resource, to use in function with resource id param, like:
public void setWidgetLayoutResource (int widgetLayoutResId)
或结果
2)是它可以动态地画出改变R.drawable.something.bmp形象?
or
2) is it possible to dynamically draw to change image in R.drawable.something.bmp?
这一切都在setWidgetLayoutResource()小部件的颜色改变,任何颜色,不固定的混凝土资源的颜色
All this for change color of widget in setWidgetLayoutResource() to any color, not fixed as color of concrete resource
推荐答案
我自己的答案
此问题是相对于我的其他:的Android preferenceScreen
而我做的是这样的:
This question is relative to my other: Android PreferenceScreen and I was do it in this way:
ColorLinesView.java
public class ColorLinesView extends View
{
private static GradientDrawable gdDefault = new GradientDrawable();
public static int fillColor;
public ColorLinesView(Context context, AttributeSet attrs)
{ super(context, attrs);
}
@Override protected void onDraw(Canvas cv)
{
gdDefault.setColor(fillColor);
gdDefault.setCornerRadius(4);
gdDefault.setStroke(2, 0xffbbbbbb);
this.setBackgroundDrawable(gdDefault);
}
}
color_lines_accesory.xml
<?xml version="1.0" encoding="utf-8"?>
<android.swp.ColorLinesView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/colorBoxLines"
android:layout_width="52dp"
android:layout_height="26dp"
android:gravity="right"
android:layout_marginRight="6dp" />
最后,而编程创建preferenceScreen,之后添加类preference一些preF
and finally while programmatically create PreferenceScreen, after add category preference "somePref":
ColorLinesView.fillColor = 0xff00ff00; // examply green
somePref.setWidgetLayoutResource(R.layout.color_lines_accesory);
和相同的两条线(新彩)在preferenceClickListener()的一些preF的范畴,用拾色器后变色。
and the same two lines (with new color) in OnPreferenceClickListener() for "somePref" category, after using color picker to change color.
结果:
