有兩種方式
public class MainActivity extends AppCompatActivity implements View.OnClickListener { private String url = "http://172.16.52.17:8080/UploadDemo4/UploadFile"; private Button get_photo; private GridView gv; private List<Bitmap> imageUrl; private Bitmap bm; private MyAdapter myAdapter; private Button up_load; private Intent intent; private String imagePath; private List<String> list; private File file; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); initData(); initAdapter(); } private void initAdapter() { myAdapter = new MyAdapter(imageUrl, bm, this); gv.setAdapter(myAdapter); } private void initData() { imageUrl = new ArrayList<>(); list = new ArrayList<>(); } private void initView() { get_photo = (Button) findViewById(R.id.get_photo); get_photo.setOnClickListener(this); gv = (GridView) findViewById(R.id.gv); up_load = (Button) findViewById(R.id.up_load); up_load.setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.get_photo:
