Question

我知道我可以使用下面的代码在系统布局中显示图像，但我希望在我的自定义布局中显示图像，我该怎么做？谢谢！

public void onClick(View v) {
                    // TODO Auto-generated method stub
                    int id = v.getId();
                    Intent intent = new Intent();
                    intent.setAction(Intent.ACTION_VIEW);
                    intent.setDataAndType(Uri.parse("file://" + arrPath[id]), "image/*");
                    startActivityForResult(intent,ForBrowse);
}



<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/border_ui"
    android:orientation="vertical"
    android:paddingTop="3dip" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <Button
        android:id="@+id/btnClose"
        style="@style/myTextAppearance"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="@string/myreturn" />

</LinearLayout>

Answer 1

完成xml后，

只需添加以下代码即可将图像设置为imageview

ImageView img = (ImageView)findViewById(R.id.Imageview1);
img.setImageResource(R.drawable.yourimage);

Answer 2

Intent intent = new Intent(this, YourImageViewerActivity.class);
Bundle bundle = new Bundle(); 
bundle.putString("data", yourImageUri); 
intent.putExtras(bundle); 
startActivity(intent);

onCreate（）方法：

Bundle bundle = getIntent().getExtras();
String yourImageUri= bundle.getString("data");
Bitmap bitmap = BitmapFactory.decodeFile(yourImageUri);
ImageView myImageView = (ImageView)findViewById(R.id.imageView1);
myImageView.setImageBitmap(bitmap);

Answer 3

如果以上分辨率不合适，那么试试这个，它会从您想要的页面加载图像：

String url = "file://" + arrPath[id]), "image/*";
Bitmap bmp = fromURL(url);
imgview.setImageBitmap(bmp);
and write this function:

public static Bitmap fromURL(String src) {  
        try {
            URL url = new URL(src);
            HttpURLConnection connection = (HttpURLConnection) url
                    .openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap mybitmap = BitmapFactory.decodeStream(input);

            return bitmap;

        } catch (Exception exception1) {
            return null;
        }

Answer 4

如果您尝试从XML文件添加图像到布局

<ImageView
    android:id="@+id/imageView1"
    android:src="@drawable/book"    <- Change this to your drawable item
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1" />

我可以在自定义布局中显示图像吗？
