发图片(布局+代码)
1.定义权限
String[] permiss={Manifest.permission.CAMERA,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE};
2.点击按钮中,展开popwindow
tou2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
View p = View.inflate(PersonalDataActivity.this, R.layout.popchange, null);
final PopupWindow popupWindow = new PopupWindow(p, ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.WRAP_CONTENT, true);
popupWindow.setBackgroundDrawable(getResources().getDrawable(R.mipmap.ic_launcher));
popupWindow.showAtLocation(v, Gravity.RIGHT | Gravity.BOTTOM, 10,10);
popupWindow.setOutsideTouchable(true);
popupWindow.setFocusable(true);
Button cream = p.findViewById(R.id.cream);
Button photo = p.findViewById(R.id.photo);
Button centel = p.findViewById(R.id.centel);
//相机点击
cream.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PermissionsUtils.getInstance().chekPermissions(PersonalDataActivity.this, permiss, new PermissionsUtils.IPermissionsResult() {
@Override
public void passPermissons() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.addCategory("android.intent.category.DEFAULT");
startActivityForResult(intent, 101);
popupWindow.dismiss();
}
@Override
public void forbitPermissons() {
}
});
}
});
//图片点击
photo.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PermissionsUtils.getInstance().chekPermissions(PersonalDataActivity.this, permiss, new PermissionsUtils.IPermissionsResult() {
@Override
public void passPermissons() {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 202);
popupWindow.dismiss();
}
@Override
public void forbitPermissons() {
}
});
}
});
//取消
centel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
popupWindow.dismiss();
}
});
}
});
3.重写onActivityResult方法
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 101) {
Bitmap bitmap = data.getParcelableExtra("data");
tou2.setImageBitmap(bitmap);
//将bitmap类型转换成uri
Uri uri = Uri.parse(MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, null, null));
addHeaderPhoto(uri);
}
if (requestCode == 202) {
Uri uri = data.getData();
addHeaderPhoto(uri);
tou2.setImageURI(uri);
}
}
4.定义一个addHeaderPhoto方法
private void addHeaderPhoto(Uri uri) {
//将uri类型转换成file
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String string = cursor.getString(columnIndex);
File file = new File(string);
//将file类型转换成part
RequestBody requestBody = RequestBody.create(MediaType.parse("image/jpg"), file);
MultipartBody.Part part = MultipartBody.Part.createFormData("image", file.getName(), requestBody);
Map map = new HashMap<>();
map.put("userId",userId+"");
map.put("sessionId",sessionId);
//Retrofit解析
RetrofitUtils.getGetInstance().upLoadImage(InterFace.CHANGEIMG_URL,map,part).setOkHttpListener(new RetrofitUtils.OkHttpListener() {
@Override
public void success(String jsons) {
Gson gson=new Gson();
UpdataImgBean updataImgBean = gson.fromJson(jsons, UpdataImgBean.class);
Toast.makeText(PersonalDataActivity.this, "嘿!" + updataImgBean.getMessage(), Toast.LENGTH_SHORT).show();
Log.d( "111222",updataImgBean.getHeadPath());
}
@Override
public void error(String error) {
}
});
}
5.popwindow布局
