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");
}

}
