Android Image Dialog/Popup

Question

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" /> 

Answer 1

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(); } 

Answer 2

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>
