首先Activity:A跳转到Activity:B
public static final int REQUEST_SEARCH = 100;Intent intent = new Intent(getActivity(), MapSearchDeviceActivity.class);startActivityForResult(intent, REQUEST_SEARCH);@Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == Activity.RESULT_OK) {//判断是否返回成功 if (requestCode == REQUEST_SEARCH) {//判断来自哪个Activity jd = Float.parseFloat(data.getStringExtra("jd")); wd = Float.parseFloat(data.getStringExtra("wd")); } } }Activity:B
Intent intent = new Intent();intent.putExtra("jd", dataBeanList.get(position).getJd());intent.putExtra("wd", dataBeanList.get(position).getWd());MapSearchDeviceActivity.this.setResult(RESULT_OK, intent);MapSearchDeviceActivity.this.finish();销毁B后A中得到B获取的值。
