仍使用 XML 视图时绘制位图

发布于 2024-10-20 15:37:46 字数 410 浏览 1 评论 0原文

因此，我使用 main.xml 作为程序中的视图，但我仍然需要能够通过编程将 bimaps/drawables 添加到屏幕。有什么办法可以做到这一点吗？

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

这就是我的 onCreate 的样子（但有很多用于应用程序目的的代码）。

无论如何，是否可以在我当前视图的顶部添加视图或画布？

我对 Android 的位图和可绘制对象很陌生，很抱歉，如果这是众所周知的，但我在任何地方都找不到像样的答案：P

谢谢，布兰登

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);
 }

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

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

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

Thanks,
Brandon

在 xml 中为框架布局（或要放置视图的另一个布局）创建一个 Id
也许你可以让你的 onCreate() 像这样：

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);

}

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);

}
