声明为Android联系人照片大小的常量？

Question

我的Nexus S上的联系人照片是96x96.我真的不想将这些知识"烘焙"到我的代码中 - 是否有一个声明这个的常量？我看了,但似乎找不到一个.

Answer 1

在android 2.3+中有一个ThumbnailUtils类

/**
 * Constant used to indicate the dimension of micro thumbnail.
 * @hide Only used by media framework and media provider internally.
 */
public static final int TARGET_SIZE_MICRO_THUMBNAIL = 96;

但@hide隐藏了它.

查看Contacts app源代码,文件AttachImage.java我发现了另一个有趣的事情:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent result) {
    // omitted

    if (requestCode == REQUEST_PICK_CONTACT) {
        // A contact was picked. Launch the cropper to get face detection, the right size, etc.
        // TODO: get these values from constants somewhere
        Intent myIntent = getIntent();
        Intent intent = new Intent("com.android.camera.action.CROP", myIntent.getData());
        if (myIntent.getStringExtra("mimeType") != null) {
            intent.setDataAndType(myIntent.getData(), myIntent.getStringExtra("mimeType"));
        }
        intent.putExtra("crop", "true");
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("outputX", 96);
        intent.putExtra("outputY", 96);
        intent.putExtra("return-data", true);
        startActivityForResult(intent, REQUEST_CROP_PHOTO);

那个TODO和那些intent.putExtra说了很多,即使有一个缩略图大小常量,它也没有在联系人应用程序中使用.
