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);
}}
