调用系统相册

protected void gotoXC() {        Intent intent=new Intent(Intent.ACTION_GET_CONTENT);        intent.addCategory(Intent.CATEGORY_OPENABLE);        intent.setType("image/*");        intent.putExtra("crop", "true");        intent.putExtra("aspectX", 1);        intent.putExtra("aspectY", 1);        intent.putExtra("outputX", 80);        intent.putExtra("outputY", 80);        intent.putExtra("return-data", true);        startActivityForResult(intent, 0);    }

调用照相机

protected void gotoXJ() {        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);          startActivityForResult(intent, 1);     }

获取图片保存到本地 并显示到imageview

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==Activity.RESULT_OK){
Log.e(“onActivityResult”, resultCode+”“);
String sdStatus = Environment.getExternalStorageState();
if (!sdStatus.equals(Environment.MEDIA_MOUNTED)) { // 检测sd是否可用
Log.i(“TestFile”,
“SD card is not avaiable/writeable right now.”);
Log.e(“onActivityResult”, “SD card is not avaiable/writeable right now”);
return;
}

            String name = new DateFormat().format("yyyyMMdd_hhmmss",Calendar.getInstance(Locale.CHINA)) + ".jpg";                 Bundle bundle = data.getExtras();              Bitmap bitmap = (Bitmap) bundle.get("data");// 获取相机返回的数据，并转换为Bitmap图片格式              FileOutputStream b = null;              File file = new File("/sdcard/myImage/");              file.mkdirs();// 创建文件夹              String fileName = "/sdcard/myImage/"+name;              try {                  b = new FileOutputStream(fileName);                  bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把数据写入文件              } catch (FileNotFoundException e) {                  e.printStackTrace();              } finally {                  try {                      b.flush();                      b.close();                  } catch (IOException e) {                      e.printStackTrace();                  }              }              Log.e("onActivityResult", "----------------001");            //===调用接口保存头像 成功更换头像            if(true){                 Log.e("onActivityResult", "---------------------002");                Drawable drawable =new BitmapDrawable(bitmap);                image_avtr.setBackground(null);                image_avtr.setImageBitmap(null);                image_avtr.setImageDrawable(null);                image_avtr.setBackgroundDrawable(null);                image_avtr.setBackground(drawable);            }else{                ToastUtils.Toas(getApplicationContext(), "上传头像失败，请稍后再试");    }else{        ToastUtils.Toas(getApplicationContext(), "照片获取失败，请稍后再试");    }}
