第一行代码中相机问题

第一行代码中相机的源码存在错误，选择相册的时候会崩，解决方法及步骤：

1、将chooseFromAlbum点击事件中的

Intent intent = new Intent("android.intent.action.GET_CONTENT")

改为

Intent intent = new Intent("android.intent.action.PICK")

2、将chooseFromAlbum点击事件中的

startActivityForResult(intent,CROP_PHOTO)

改为

startActivityForResult(intent,TAKE_PHOTO)

因为case TAKE_PHOTO中的intent是用来启动裁剪程序的。

3.将case TAKE_PHOTO中的代码修改为如下：

case TAKE_PHOTO:
                if (resultCode == RESULT_OK) {
                    if (data != null) {
                        imageUri = data.getData();
                    }
                    Intent intent = new Intent("com.android.camera.action.CROP");
                    intent.setDataAndType(imageUri, "image/*");
                    intent.putExtra("scale", true);
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                    startActivityForResult(intent, CROP_PHOTO);
                }
                break;

完整代码如下：

    public static final int TAKE_PHOTO = 1;
    public static final int CROP_PHOTO = 2;
    private Uri imageUri;
    private ImageView picture;
        /**
         * 拍照按钮点击事件
         */
        btn_take_photo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Date date=new Date();
                Long photo_name=date.getTime();
                File outputImage = new File(Environment.getExternalStorageDirectory(),
                        photo_name+".jpg");
                photos.add(outputImage);
                try {
                    if (outputImage.exists()) {
                        outputImage.delete();
                    }
                    outputImage.createNewFile();
                } catch (IOException e) {

                intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                startActivityForResult(intent, TAKE_PHOTO);
            }
        });
        /**
