尝试了很多方法,但没有达到积极的结果。 在TableLayout中有ImageView:
<TableLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/photo_layout_background"
android:stretchColumns="*" >
<TableRow
android:background="@color/photo_layoutrow_background"
android:layout_weight="1"
android:layout_marginBottom="4dp"
android:gravity="center" >
<ImageView
android:id="@+id/photo1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginRight="4dp"
android:src="@drawable/icon_photo"
android:background="@color/photo_background"
android:clickable="true"
android:onClick="addPhoto_Click"/>
当您点击ImageView
提供获取图片的标准程序并且文件保存在SD卡上时:
public void addPhoto_Click(View v){
select_add_photo_id = v.getId();
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, generateFilePhotoUri());
startActivityForResult(takePictureIntent, CAMERA_RESULT);
}
@SuppressLint("SimpleDateFormat")
private Uri generateFilePhotoUri() {
File file = null;
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
file = new File(MEDIA_PATH + String.valueOf(id) + File.separator + timeStamp + ".jpg");
select_add_photo_file = file.getAbsolutePath();
return Uri.fromFile(file);
}
照片保存通常存储在变量select_add_photo_id id ImageView中,点击select_add_photo_file变量保存文件照片的完整路径。
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_RESULT) {
if (resultCode == RESULT_OK){
ImageView imgView = (ImageView) findViewById(select_add_photo_id);
imgView.setImageDrawable(Drawable.createFromPath(select_add_photo_file));
}
}
}
但是当文件只获得带有背景和增加大小的ImageView ImageView时。摄影未加载。没有错误。
还在设置照片吗?
答案 0 :(得分:1)
Bitmap photo = null;
Uri photoUri = data.getData();
String filePath = "";
if (photoUri != null) {
//mFilePath = getRealPathFromURI(photoUri);
filePath = getRealPathFromURI(photoUri);
photo = BitmapFactory.decodeFile(photoUri.getPath());
}
if (photo == null) {
Bundle extra = data.getExtras();
if (extra != null) {
photo = (Bitmap)extra.get("data");
