Android在TextView上显示图片点击

Question

This is probably really easy for most of you guys, but since I'm still a beginner I'm having problems figuring it out. Anyway, I want a picture to show when a textview is clicked. I know how to set up the onClickListener, but dont know how to make the picture show up as the result of the text being clicked. What method would I use for it? Its a fixed image that I have in my drawable folder. Thanks

Answer 1

You can create an ImageView inside your layout where you want to show your image and you can set imageView's visibility attribute to invisible to make it invisible to the screen.

example:

<ImageView
    android:id="@+id/imageViewCompass"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/mwImage"
    android:visibility="invisible" />

Inside the OnClick of your button you can then set the Imageview visility to visible;

yourImageView.setVisibility(View.VISIBLE);

Answer 2

After you inserted your image into drawables, set an ImageView in your .xml as:

<ImageView
android:layout_width=""
android:layout_height=""
android:id="@+id/image"
android:src="@drawable/imagelocation"
android:visibility="invisible" />

Then in your class Activity, do this:

public class Templates extends Activity {

Button btnimage;
ImageView image;

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

image = (ImageView) findViewById(R.id.image);
btnimage = (Button) findViewById(R.id.btnimage);

btnimage.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {

image.setVisibility(View.VISIBLE);

        }
    });
}

UPDATE:

Yes, it is possible to show up ImageView on dialog. Follow this:

Dialog settingsDialog = new Dialog(this);
settingsDialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
settingsDialog.setContentView(getLayoutInflater().inflate(R.layout.image_layout, null));
settingsDialog.show();

Then your .xml should look something like:

<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="Show Image" android:onClick="dismissListener"/>
</LinearLayout>
