使用步骤

1. 在project的build.gradle添加如下代码(如下图)

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

2. 在Module的build.gradle添加依赖

  compile 'com.github.open-android:ImageSelector:0.1.0'

3. 配置如下权限

 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 <uses-permission android:name="android.permission.CAMERA"/>

4.复制如下代码到xml布局

 <Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:onClick="selectImg"
    android:text="@string/image_selector_select_image" />

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:id="@+id/content"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </ScrollView>

5.复制如下代码到java类当中

public class MainActivity extends AppCompatActivity {

    private static final int REQUEST_CODE_SELECT_IMG = 1;
    private static final int MAX_SELECT_COUNT = 9;
    private TextView mContentTv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
    }

    private void initView() {
        mContentTv = (TextView) findViewById(R.id.content);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_CODE_SELECT_IMG) {
            showContent(data);
            return;
        }

        super.onActivityResult(requestCode, resultCode, data);
    }

    private void showContent(Intent data) {
        List<String> paths = ImageSelector.getImagePaths(data);
        if (paths.isEmpty()) {
            mContentTv.setText(R.string.image_selector_select_none);
            return;
        }

        mContentTv.setText(paths.toString());
    }

    public void selectImg(View v) {
        ImageSelector.show(this, REQUEST_CODE_SELECT_IMG, MAX_SELECT_COUNT);
    }}
