图片选择器（支持相册和相机），只需一步实现

来源：互联网发布：yii2.0开源项目源码编辑：程序博客网时间：2024/05/20 15:21

写了一段时间的代码，发现老是做些重复的工作，效率低。其实很多是可以优化封装成库，下次使用时，能快速集成，减少开发时间。
图片选择器是很多app都用到的，我给他封装了一下，只需一步。

只要继承BaseCameraActivity，设置下监听器就好了

public class MainActivity extends BaseCameraActivity implements BaseCameraActivity.OnSelectPhotoInterface {    @Bind(R.id.imageview)    public ImageView mIndexIv;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        setOnSelectPhotoListener(this);    }    @OnClick(R.id.gallery_select_btn)    public void clickGallerySelect(){//        startChoosePhotoByDialogMode();        startChoosePhotoByInlineMode();    }    @Override    public void onCropImageCancel() {    }    @Override    public void onCropImageDone(String imagePath) {        Bitmap bitmap = BitmapUtils.getBitmapAutoResize(imagePath, this);        if(bitmap != null){            mIndexIv.setImageBitmap(bitmap);        }    }    @Override    protected void onDestroy() {        ButterKnife.unbind(this);        super.onDestroy();    }}

这是主activity，就这么简单。

SelectPhotoActivity，选择图库

public class SelectPhotoActivity extends Activity implements PhotoAsyncTask.LoaderCallbacks, View.OnClickListener{    public static final String KEY_INTENT_ALBUM_LIST = "key_intent_album_list";    public static final String KEY_INTENT_IMAGE_LIST = "key_intent_image_list";    public static final String KEY_SAVE_ALBUM_LIST = "key_save_album_list";    public static final String KEY_SAVE_IMAGE_LIST = "key_save_image_list";    public static final String KEY_IS_DIALOG_MODE = "KEY_IS_DIALOG_MODE";    private static final int INTENT_RESULT_JUMP_ABLUM_PAGE = 101;    private GridView mRecyclerView;    private SelectPhotoAdapter mAdapter;    private ArrayList<ImageItem> mDataList = new ArrayList<ImageItem>();    private ArrayList<ImageBucket> mBucketList = new ArrayList<ImageBucket>();    private boolean mIsDialogMode = true;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_select_photo);        initView();        initWidget();        setupListener();        loadData(savedInstanceState);    }    private void initView(){        mRecyclerView = (GridView)findViewById(R.id.recyclerview);    }    private void initWidget(){        initParams();        mAdapter = new SelectPhotoAdapter(this, mDataList);        mRecyclerView.setAdapter(mAdapter);    }    private void initParams(){        Intent intent = getIntent();        if(intent != null){            mIsDialogMode = intent.getBooleanExtra(KEY_IS_DIALOG_MODE, true);        }    }    private void setupListener(){        findViewById(R.id.album_tv).setOnClickListener(this);        findViewById(R.id.close_ib).setOnClickListener(this);        mAdapter.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(int position) {                handleItemClick(position);            }        });    }    private void handleItemClick(int position){        Intent data = new Intent();        ImageItem item = mDataList.get(position);        String path = item.getPath();        if(item.getIsCamera() == 1){            path = "";        }        data.putExtra(BaseCameraActivity.INTENT_KEY_IMAGE_PATH, path);        setResult(RESULT_OK, data);        finish();    }    private void loadData(Bundle savedInstanceState){        if(savedInstanceState == null){            new PhotoAsyncTask(this, this, !mIsDialogMode).execute();        }else{            onRestoreInstance(savedInstanceState);        }    }   private void onRestoreInstance(Bundle savedInstanceState){       ArrayList<ImageItem> dataList = savedInstanceState.getParcelableArrayList(KEY_SAVE_IMAGE_LIST);       ArrayList<ImageBucket> bucketList = savedInstanceState.getParcelableArrayList(KEY_SAVE_ALBUM_LIST);       DebugTools.d("save2 onRestoreInstance dataList size: " + dataList.size() + " bucketList size: " + bucketList.size());       mDataList.addAll(dataList);       mAdapter.notifyDataSetChanged();       mBucketList.addAll(bucketList);   }    @Override    protected void onSaveInstanceState(Bundle outState) {        DebugTools.d("save2 onSaveInstanceState");        outState.putParcelableArrayList(KEY_SAVE_IMAGE_LIST, mDataList);        outState.putParcelableArrayList(KEY_SAVE_ALBUM_LIST, mBucketList);        super.onSaveInstanceState(outState);    }    @Override    public void onLoadFinished(ArrayList<ImageItem> dataList, ArrayList<ImageBucket> bucketList) {        mDataList.clear();        mDataList.addAll(dataList);        mAdapter.notifyDataSetChanged();        mBucketList.addAll(bucketList);    }    @Override    public void onClick(View v) {        int id = v.getId();        if(id == R.id.album_tv){            handleClickAlbum();        }else if(id == R.id.close_ib){            finish();        }    }    private void handleClickAlbum(){        jump2AlbumPage(mBucketList);    }    private void jump2AlbumPage(ArrayList<ImageBucket> bucketList){        Intent intent = new Intent(this, SelectAlbumActivity.class);        intent.putParcelableArrayListExtra(KEY_INTENT_ALBUM_LIST, bucketList);        startActivityForResult(intent, INTENT_RESULT_JUMP_ABLUM_PAGE);    }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        switch (requestCode) {            case INTENT_RESULT_JUMP_ABLUM_PAGE:                hanleActivityBackFromAblum(data);                break;        }    }    private void hanleActivityBackFromAblum(Intent data){        if(data == null){            return;        }        findViewById(R.id.album_tv).setVisibility(View.INVISIBLE);        ArrayList<ImageItem> dataList = data.getParcelableArrayListExtra(KEY_INTENT_IMAGE_LIST);        if(dataList != null && dataList.size() > 0){            mDataList.clear();            mDataList.addAll(dataList);            mAdapter.notifyDataSetChanged();        }    }}

SelectAlbumActivity，选择图库里面的专辑

public class SelectAlbumActivity extends Activity {    public static final String KEY_SAVE_IMAGE_LIST = "key_save_image_list";    private GridView mRecyclerView;    private SelectAlbumAdapter mAdapter;    private ArrayList<ImageBucket> mDataList = new ArrayList<ImageBucket>();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_select_album);        initView();        initWidget();        setupListener();        loadData(savedInstanceState);    }    private void initView(){        mRecyclerView = (GridView)findViewById(R.id.recyclerview);    }    private void initWidget(){        mAdapter = new SelectAlbumAdapter(this, mDataList);        mRecyclerView.setAdapter(mAdapter);    }    private void setupListener(){        mAdapter.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(int position) {                handleItemClick(position);            }        });        findViewById(R.id.close_ib).setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                finish();            }        });    }    private void handleItemClick(int position){        Intent data = new Intent();        data.putParcelableArrayListExtra(SelectPhotoActivity.KEY_INTENT_IMAGE_LIST, mDataList.get(position).getDataList());        setResult(RESULT_OK, data);        finish();    }    private void loadData(Bundle savedInstanceState){        if(savedInstanceState == null){            initParams();        }else{            onRestoreInstance(savedInstanceState);        }    }    private void onRestoreInstance(Bundle savedInstanceState){        ArrayList<ImageBucket> bucketList = savedInstanceState.getParcelableArrayList(KEY_SAVE_IMAGE_LIST);        mDataList.addAll(bucketList);        mAdapter.notifyDataSetChanged();    }    @Override    protected void onSaveInstanceState(Bundle outState) {        outState.putParcelableArrayList(KEY_SAVE_IMAGE_LIST, mDataList);        super.onSaveInstanceState(outState);    }    private void initParams(){        Intent intent = getIntent();        if(intent != null){            ArrayList<ImageBucket> dataList = intent.getParcelableArrayListExtra(SelectPhotoActivity.KEY_INTENT_ALBUM_LIST);            mDataList.clear();            mDataList.addAll(dataList);            mAdapter.notifyDataSetChanged();        }    }}

SelectCameraGalleryDialog，弹出是选择图库，还是相机的对话框

public class SelectCameraGalleryDialog extends Dialog implements View.OnClickListener{    private Context mContext;    private TextView mCameraTv;    private TextView mGalleryTv;    public SelectCameraGalleryDialog(Context context) {        super(context, R.style.DialogNormalStyle);        mContext = context;    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        View view = LayoutInflater.from(mContext).inflate(R.layout.library_camera_dialog_select_camera_gallery, null);        initView(view);        initWidget();        setupListener(view);    }    private void initView(View view){        mCameraTv = (TextView)view.findViewById(R.id.camera_type_tv);        mGalleryTv = (TextView)view.findViewById(R.id.gallery_type_tv);        setContentView(view);    }    private void setupListener(View view){        mCameraTv.setOnClickListener(this);        mGalleryTv.setOnClickListener(this);        view.findViewById(R.id.cancel_tv).setOnClickListener(this);    }    private void initWidget(){        initWidthHeight();    }    private void initWidthHeight(){        int[] arr = getScreenWidthHeight(mContext);        Window window = this.getWindow();        WindowManager.LayoutParams params = window.getAttributes();        params.width = arr[0] * 8 / 9;        window.setAttributes(params);        window.setGravity(Gravity.BOTTOM);    }    private int[] getScreenWidthHeight(Context context) {        int[] posArr = new int[2];        if (context == null) {            return posArr;        }        DisplayMetrics mDisplayMetrics = new DisplayMetrics();        ((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(mDisplayMetrics);        int width = mDisplayMetrics.widthPixels;        int height = mDisplayMetrics.heightPixels;        posArr[0] = width;        posArr[1] = height;        return posArr;    }    @Override    public void onClick(View v) {        if(v.getId() == R.id.camera_type_tv){            handleClickCameraGallery(true);        }else if(v.getId() == R.id.gallery_type_tv){            handleClickCameraGallery(false);        }else if(v.getId() == R.id.cancel_tv){            dismiss();        }    }    private void handleClickCameraGallery(boolean isCamera){        if(mListener != null){            mListener.onSelectCameraGallery(isCamera);        }        dismiss();    }    public OnSelectCameraGalleryListener mListener;    public void setOnSelectCameraGalleryListener(OnSelectCameraGalleryListener listener){        mListener = listener;    }    public interface OnSelectCameraGalleryListener{        public void onSelectCameraGallery(boolean isCamera);    }}

其实也不难，只是封装了一下，下次方便使用
