绘制位图时仍使用XML查看 [英] Draw Bitmap When Still Using XML View

问题描述

所以，我用我的main.xml在我的程序的视图，但我还需要能够通过编程来bimaps /绘图资源添加到屏幕上。有没有办法做到这一点？

So I am using my main.xml as a view in my program but I still need to be able to add bimaps/drawables to the screen through programming. Is there any way to do that?

 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
 }

这是有点儿什么我的onCreate样子（但有很多code为应用程序的目的）。

That is kinda what my onCreate looks like (but with a lot of code for the purpose of the app).

反正是有可能加我当前视图的视图或画布ONTOP？

Is there anyway to maybe add a View or Canvas ONTOP of my current view?

我是新来的位图和绘图为Android很抱歉，如果这是众所周知的，但我不能在任何地方找到一个体面的答案：P

I am new to bitmaps and drawables for android so sorry if this is commonly known, but I can't find a decent answer anywhere :P

谢谢，

推荐答案

创建（如果你想要把视图或另一个布局）一个标识在XML中的FrameLayout
也许你可以有你的onCreate（）是这样的：

Create a Id to a framelayout in the xml (or another layout where you want to put the view) Maybe you can have your onCreate() something like this:

public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);

   //Init the framelayout from xml by id
   FrameLayout myFrameLayout = (FrameLayout) findViewById(R.id.myFrameLayout);

   //Create a new ImageView
   img_icon = new ImageView(this);
   img_icon.setImageResource(R.drawable.icon);
   img_icon.setAdjustViewBounds(true);
   img_icon.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));

   //Add the newly created ImageView
   myFrameLayout.addView(img_icon);

}
