的onActivityResult没有得到所谓的,而在Android的使用画廊 [英] onactivityresult not getting called while using Gallery in android
本文介绍了的onActivityResult没有得到所谓的,而在Android的使用画廊的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在我的Android应用程序中使用这个code开一家画廊。
I am opening a gallery in my Android Application using this code.
Intent intent = new Intent(Intent.ACTION_PICK, Media.EXTERNAL_CONTENT_URI);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivityForResult(intent, GALLERY);
它打开图片库,但,当我从那里的收盘也不过不叫选择任何图片的onActivityResult
方法。
方法是这里....
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.v(TAG, "requestCode = "+requestCode+" resultCode = "+resultCode);
Log.v(TAG, "inside onActivityResult");
if (requestCode == GALLERY || requestCode == CAMERA) {
if (resultCode == RESULT_OK)
{
Log.v(TAG, "inside onActivityResult OK ");
Log.v("log_tag", "onactivity result: " + requestCode);
if(requestCode == CAMERA)
{
Log.v(TAG, "inside onActivityResult Camera");
file = getTempFile(this.getParent());
try {
m_bmOCRBitmap = Media.getBitmap(getContentResolver(), Uri.fromFile(file) );
FileOutputStream out = new FileOutputStream(file);
int width = m_bmOCRBitmap.getWidth();
int height = m_bmOCRBitmap.getHeight();
if(width>height)
{
calwidth = (int)((width * 250)/height);
calheight = 250;
}
else
{
calheight = (int)((height * 200)/width);
calwidth = 200;
}
Log.v(TAG, "calwidth = "+calwidth+" calheight = "+calheight);
bitmap = Bitmap.createScaledBitmap(m_bmOCRBitmap, calwidth, calheight, true);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
productImage.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
else if(requestCode == GALLERY)
{
Log.v(TAG, "inside onActivityResult GALARY ");
String selectedImagePath = getPath(data.getData());
file = new File(selectedImagePath);
m_bmOCRBitmap = BitmapFactory.decodeFile(selectedImagePath);
Log.v("log_tag", "selectedImagePath:" + selectedImagePath + ":" );
Log.v("log", "first image : "+m_bmOCRBitmap);
try {
FileOutputStream out = new FileOutputStream(file);
int width = m_bmOCRBitmap.getWidth();
int height = m_bmOCRBitmap.getHeight();
if(width>height)
{
calwidth = (int)((width * 250)/height);
calheight = 250;
}
else
{
calheight = (int)((height * 200)/width);
calwidth = 200;
}
bitmap = Bitmap.createScaledBitmap(m_bmOCRBitmap, calwidth, calheight, true);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
productImage.setImageBitmap(bitmap);
} catch (Exception e) {
Log.v("log_tag", "Exception: " + e.toString());
}
}
}
}
super.onActivityResult(requestCode, resultCode, data);
}
而所谓的意图是警告
the Warning while called Intent is
01-04 12:21:06.434: D/PhoneWindow(367): couldn't save which view has focus because the focused view com.android.internal.policy.impl.PhoneWindow$DecorView@4054fb60 has no id.
请注意,我已经开始这项活动从Tabgoup活动的子活动。
please note that I have started this activity as child activity from Tabgoup Activity.
请建议我。谢谢你。
推荐答案
我父类像这样添加了这个方法。
I added this Method in Parent class like this
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
ProductImageActivity activity = (ProductImageActivity)getLocalActivityManager().getCurrentActivity();
try {
activity.onActivityResult(requestCode, resultCode, data,0);
} catch (Exception e) {
e.printStackTrace();
}
}
在我目前的类,我开始喜欢这个新的意图。
and in my current class I started new Intent like this.
Intent intent = new Intent(Intent.ACTION_PICK, Media.EXTERNAL_CONTENT_URI);
getParent().startActivityForResult(intent, GALLERY);
