更改头像功能不像修改信息一样直接提交参数就可以，需要上传图片文件
我就直接贴代码了首先给出布局文件
<ImageViewandroid:id="@+id/iv"android:layout_width="50dp"android:layout_height="50dp"android:src="@mipmap/ic_launcher" /><Buttonandroid:id="@+id/btn1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="拍照" /><Buttonandroid:id="@+id/btn2"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="摄像" /><TextViewandroid:id="@+id/tv"android:layout_width="wrap_content"android:layout_height="wrap_content" />
然后就是上传的代码了
public class MainActivity extends AppCompatActivity implements View.OnClickListener {private Button btn1, btn2;private ImageView headIv;private TextView textView;private static final String TAG = "MainActivity";private final int IMAGE_RESULT_CODE = 2;private final int PICK = 1;private String url = "";//此处为上传图片地址，我就不写了private String imgString = "";private Intent intent;private Handler mHandler = new Handler(Looper.getMainLooper());@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);btn1 = findViewById(R.id.btn1);btn2 = findViewById(R.id.btn2);textView = findViewById(R.id.tv);headIv = findViewById(R.id.iv);btn1.setOnClickListener(this);btn2.setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.btn1:intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);startActivityForResult(intent, PICK);break;case R.id.btn2:intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);startActivityForResult(intent, IMAGE_RESULT_CODE);break;}}@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);switch (requestCode) {// 表示 调用照相机拍照case PICK:if (resultCode == RESULT_OK) {Bundle bundle = data.getExtras();Bitmap bitmap = (Bitmap) bundle.get("data");imgString = bitmapToBase64(bitmap);uploadImg();}break;// 选择图片库的图片case IMAGE_RESULT_CODE:if (resultCode == RESULT_OK) {Uri uri = data.getData();Bitmap bitmap2 = PhotoUtils.getBitmapFromUri(uri, this);imgString = bitmapToBase64(bitmap2);uploadImg();}break;}}//上传图片文件的操作public void uploadImg() {OkHttpClient okHttpClient = new OkHttpClient.Builder().build();//上传图片参数需要与服务端沟通，我就不多做解释了，我添加的都是我们服务端需要的//你们根据情况自行更改//另外网络请求我就不多做解释了FormBody body = new FormBody.Builder().add("dir", "c/image").add("data", imgString).add("file", "headicon").add("ext", "jpg").build();Request request = new Request.Builder().url(url).post(body).build();okHttpClient.newCall(request).enqueue(new Callback() {@Overridepublic void onFailure(Call call, IOException e) {}@Overridepublic void onResponse(Call call, Response response) throws IOException {final String data = response.body().string();Gson gson = new Gson();final Beans bean = gson.fromJson(data, Beans.class);Log.d(TAG, "onResponse: " + data);mHandler.post(new Runnable() {@Overridepublic void run() { //加载图片用的Gilde框架，也可以自己自由选择，//""里面取决于服务端的返回值是否需要自行添加地址Glide.with(MainActivity.this).load(""+bean.getData().getUrl()).into(headIv);}});}});}//如上参需要64位编码可调用此方法，不需要可以忽略public static String bitmapToBase64(Bitmap bitmap) {String result = null;ByteArrayOutputStream baos = null;try {if (bitmap != null) {baos = new ByteArrayOutputStream();press(pressFormat.JPEG, 100, baos);baos.flush();baos.close();byte[] bitmapBytes = baos.toByteArray();result = Base64.encodeToString(bitmapBytes, Base64.DEFAULT);}} catch (IOException e) {e.printStackTrace();} finally {try {if (baos != null) {baos.flush();baos.close();}} catch (IOException e) {e.printStackTrace();}}return result;}}
我尽量把说明都写在了注释里，就不在这里多说了
最后把照片工具类贴出来，因为MainActivity有调用
我不写出来可能有的小伙伴因为这一个报错就不知如何处理
实体类我就不写了，因为真的太简单了
