Android开发不用存储权限进行拍照

有时平台审核严，拍照时不能获取存储。这怎么办呢，拍照功能又不能去掉。

一、思路：

得自定义Camera，然后把拍照图片存在app目录下，再刷新到手机相册

二、效果图：

三、关键代码如下：

public class SecondActivity extends AppCompatActivity {

    private ImageView iv_result;
    private Context mContext;
    private ActivityResultLauncher<Intent> launcher;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mContext = this;

        launcher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), result -> {
            if (result.getResultCode() == RESULT_OK && result.getData() != null) {
                String photoPath = result.getData().getStringExtra(CameraActivity.KEY_CONTENT_TYPE);
                Log.i("photoPath",photoPath);
                if (!TextUtils.isEmpty(photoPath)) {
                    Glide.with(mContext)
                            .load(photoPath)
                            .into(iv_result);

                }
            }
        });

        iv_result = findViewById(R.id.iv_result);

        findViewById(R.id.tv_photo).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                requestPermission(mContext, new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        startCameraActivity(mContext,CameraActivity.CONTENT_TYPE_GENERAL,launcher);
                    }
                },  new String[]{
                        Manifest.permission.CAMERA,
                } );
            }
        });


    }

    /**
     * 身份证取景拍照
     */
    public static void startCameraActivity(Context mContext,String type, ActivityResultLauncher<Intent> launcher) {
        Intent intent = new Intent(mContext, CameraActivity.class);
        //intent.putExtra(CameraActivity.KEY_CONTENT_TYPE,CameraActivity.CONTENT_TYPE_ID_CARD_FRONT);
        intent.putExtra(CameraActivity.KEY_CONTENT_TYPE,type);
        launcher.launch(intent);
    }



    public static void requestPermission(final Context context, final View.OnClickListener successListener, String... permissions) {
        if (PermissionCheckUtil.checkPermissions(context,permissions)){
            if (null != successListener) {
                successListener.onClick(null);
            }
        } else {
            PermissionAppUtils.INSTANCE.requestPermission(context, permissions, new Consumer<Boolean>() {
                @Override
                public void accept(Boolean aBoolean) throws Throwable {
                    if (aBoolean){
                        if (null != successListener) {
                            successListener.onClick(null);
                        }
                    }
                }
            });
        }

    }
}
