基本的头像更换功能代码我就不贴了，度娘那里一大堆，我今天来说下从相册选取图片崩溃，其实网上的很多头像更换功能例子很多，适合于4.4以下的机型可能 都 没问题，但是4.4以上的就会出现如题所出现的BUG，直接 上代码吧！
view.findViewById(R.id.image_take).setOnClickListener(this);
view.findViewById(R.id.image_video).setOnClickListener(this);
// 相册
view.findViewById(R.id.image_video).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
} else {
intent.setAction(Intent.ACTION_GET_CONTENT);
};
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, PHOTO_REQUEST_GALLERY);
}
});
// 拍照
view.findViewById(R.id.image_take).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
// 判断存储卡是否可以用，可用进行存储
if (hasSdcard()) {
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(new File(Environment
.getExternalStorageDirectory(), PHOTO_FILE_NAME)));
}
startActivityForResult(intent, PHOTO_REQUEST_CAMERA);
}
});
”重要的代码我用图片来展示“

其他都 差不多了，就不多BB了，如果 有需要替换服务器上的头像也就是上传图片的代码小伙伴可以滴滴我！
