Android中多图片选择器PhotoPicker库的使用（仿微信，秒杀MultiImageSelector）自己修改的多选

<span style="font-size:18px;">public class MainActivity extends AppCompatActivity {
//  展示路径的TextView
private TextView mResultText;
//  调用相册的按钮
private Button button;
//  选择图片的路径
private ArrayList<String> mSelectPath;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
mResultText = (TextView) findViewById(R.id.result);

if (button != null) {
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
pickImage();
}
});
}
}
private void pickImage() {
//      调用相册中的相片，用Picasso展示
PhotoPicker.init(new PicassoImageLoader(), null);
//      启用相机
boolean showCamera = true;
//      最大选择5张
int maxNum = 5;
//      显示3列
int columns = 3;
Load load = PhotoPicker.load()
.showCamera(showCamera)
.filter(PhotoFilter.build().showGif(false).minSize(2 * 1024))
.gridColumns(columns);
//      传入最大选择的数量，和路径
PhotoSelectBuilder builder = load.multi().maxPickSize(maxNum).selectedPaths(mSelectPath);
builder.start(MainActivity.this);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PhotoPicker.REQUEST_SELECTED) {
if (resultCode == RESULT_OK) {
mSelectPath = data.getStringArrayListExtra(PhotoPicker.EXTRA_RESULT);
StringBuilder sb = new StringBuilder();
for (String p : mSelectPath) {
sb.append(p);
sb.append("\n");
}
mResultText.setText(sb.toString());
}
}
}
