Android Image Dialog/Popup
Is it possible to have just an image popup/come-up in an Android application? It's similar to an overriding the normal view of an AlertDialog so that it contains just an image and nothing else.
SOLUTION: I was able to find an answer thanks to @blessenm's help. Masking an activity as a dialog seems to be the ideal way. The following is the code that I have used. This dialog styled activity can be invoked as needed by the application the same way a new activity would be started
ImageDialog.java
public class ImageDialog extends Activity {
private ImageView mDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_dialog_layout);
mDialog = (ImageView)findViewById(R.id.your_image);
mDialog.setClickable(true);
//finish the activity (dismiss the image dialog) if the user clicks
//anywhere on the image
mDialog.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
}
}
your_dialog_layout.xml
<?xml version="1.0" encoding="UTF-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/image_dialog_root"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:color/transparent"
android:gravity = "center">
<ImageView
android:id="@+id/your_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src = "@drawable/your_image_drawable"/>
</FrameLayout>
It is crucial that you set the following style for the activity to accomplish this:
styles.xml
<style name="myDialogTheme" parent="@android:style/Theme.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFrame">@null</item>
<item name="android:background">@android:color/transparent</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:windowContentOverlay">@null</item>
</style>
The final step is to declare this style for the activity in the manifest as follows:
<activity android:name=".ImageDialog" android:theme="@style/myDialogTheme" />
No xml:
public void showImage() {
Dialog builder = new Dialog(this);
builder.requestWindowFeature(Window.FEATURE_NO_TITLE);
builder.getWindow().setBackgroundDrawable(
new ColorDrawable(android.graphics.Color.TRANSPARENT));
builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialogInterface) {
//nothing;
}
});
ImageView imageView = new ImageView(this);
imageView.setImageURI(imageUri);
builder.addContentView(imageView, new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
builder.show();
}
If you just want to use a normal dialog something like this should work
Dialog settingsDialog = new Dialog(this);
settingsDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
settingsDialog.setContentView(getLayoutInflater().inflate(R.layout.image_layout
, null));
settingsDialog.show();
image_layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content" android:src="YOUR IMAGE"/>
<Button android:layout_width="wrap_content" android:layout_height="wrap_content"
android:text="OK" android:onClick="dismissListener"/>
</LinearLayout>
Try the following:
It has image zoom_in/zoom_out as well.
Step 1:
Add compile 'com.github.chrisbanes.photoview:library:1.2.4'
to your build.gradle
Step 2:
Add the following xml
custom_fullimage_dialoge.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_root" android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:padding="10dp">
<ImageView android:id="@+id/fullimage" android:layout_width="fill_parent"
android:layout_height="fill_parent">
</ImageView>
<TextView android:id="@+id/custom_fullimage_placename"
android:layout_width="wrap_content" android:layout_height="fill_parent"
android:textColor="#FFF">
</TextView>
</LinearLayout>
Step 3:
private void loadPhoto(ImageView imageView, int width, int height) {
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
//dialog.setContentView(R.layout.custom_fullimage_dialog);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_fullimage_dialog,
(ViewGroup) findViewById(R.id.layout_root));
ImageView image = (ImageView) layout.findViewById(R.id.fullimage);
image.setImageDrawable(imageView.getDrawable());
image.getLayoutParams().height = height;
image.getLayoutParams().width = width;
mAttacher = new PhotoViewAttacher(image);
image.requestLayout();
dialog.setContentView(layout);
dialog.show();
}
Step 4:
user_Image.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
loadPhoto(user_Image,width,height);
}
});
You can do it easily by create a Dialog Fragment in Kotlin:
BigImageDialog.kt
class BigImageDialog():DialogFragment() {
private var imageUrl = ""
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
arguments?.let {
imageUrl = arguments.getString("url")
}
}
override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View {
val v = inflater!!.inflate(R.layout.dialog_big_image, container, false)
this.dialog.window.requestFeature(Window.FEATURE_NO_TITLE)
Picasso.get().load(imageUrl).into(v.bigImageView)
return v
}
override fun onStart() {
super.onStart()
val dialog = dialog
if (dialog != null) {
dialog.window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT)
}
}
companion object {
@JvmStatic
fun newInstance(imageUrl: String) =
BigImageDialog().apply {
arguments = Bundle().apply {
putString("url", imageUrl)
}
}
}
}
dialog_big_image.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/bigImageView"
android:layout_width="0dp"
android:layout_height="0dp"
android:scaleType="centerCrop"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
Opening Dialog:
"smallImageView".setOnClickListener { BigImageDialog.newInstance("image url").show(fragmentManager,"") }
