问题描述

无论我怎么努力，我不能把我的是从一个SOAP服务传递给我的Android模拟器图像的宽度和高度。我使用的ImageView如下：

No matter what I try, I cannot set the width and height of my image that is passed from a soap service to my android emulator. I'm using an ImageView as follows:

            byte[] bloc = Base64.decode(result, Base64.DEFAULT);
            Bitmap bmp = BitmapFactory.decodeByteArray(bloc,0,bloc.length);
            ImageView image = new ImageView(this);
            image.setImageBitmap(bmp);
            image.setLayoutParams(
                    new LinearLayout.LayoutParams(
                            LinearLayout.LayoutParams.WRAP_CONTENT,
                            LinearLayout.LayoutParams.WRAP_CONTENT));
            image.getLayoutParams().height = 100;
            image.getLayoutParams().width = 100;
            setContentView(image);

在上面的code，我试图手动设置，有一个259px宽194px高度JPEG图像的宽度和高度。

In the above code, I am attempting to set the width and height manually, of a jpeg image that has a 259px width and 194px height.

在/res/layout/main.xml看起来像

The /res/layout/main.xml looks like

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:weightSum="1" android:id="@+id/llid">
</LinearLayout>

在尝试一些下面的答案办法，我只是看到我的模拟器以下

After trying some of the approaches in below's answers, I just see the following on my emulator

我甚至不知道如果我采取的做法是正确的。大多数其他的解决方案，我发现从搜索论坛不为我工作。任何建议将是巨大的。

I'm not even sure if the approach I am taking is correct. Most other solutions I have found from searching the forums don't work for me. Any suggestions would be great.

推荐答案

试试这样。做一个使用 yourBitmap.getWidth（）和 .getHeight（）

Try like this. Make a use of yourBitmap.getWidth() and .getHeight()

  image.setLayoutParams(
              new LinearLayout.LayoutParams(
                     bmp.getWidth(),
                     bmp.getHeight()));

编辑：

现在您已设置了LP的ImgView，你必须做的第一件事就是将它添加到布局

Now you have set the LP for the ImgView, the first thing you have to do is to add it to the layout

的LinearLayout LL =（的LinearLayout）findViewById（R.layout.llid）;

现在你可以直接增加你的观点，或者你可以像分离的参数和 .addView（视图，则params）或 .addView（查看）; 您的通话

Now you can either add your view straight or you can do it like separating the parameters and adding it with .addView(view, params) or .addView(View); Your call.

让你做

ll.addView（图像）;
