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");
    }

}
