Adding ImageView to the Layout programmatically

Question

I want to create images which will go down from the upper part of the screen.

For up to today I have this:

ImageView mario = (ImageView) findViewById         


        

Answer 1

You can create a layout with something like

View view = (View) findViewById(R.layout.current_layout); //the layout you set in `setContentView()`
LinearLayout picLL = new LinearLayout(CurrentActivity.this);
picLL.layout(0, 0, 100, 0);
picLL.setLayoutParams(new LayoutParams(1000, 60));
picLL.setOrientation(LinearLayout.HORIZONTAL);
((ViewGroup) view).addView(picLL);

What parameters you pass in layout() are obviously going to depend on what you want. Then you can create separate Views to add to the Layout you just created. But I highly advise reading through the docs to understand what all can be done here.

ViewGroup

View

Edit

ImageView myImage = new ImageView(this);
picLL.addView(myImage);
//set attributes for myImage;

Answer 2

Using following code you can add image dynamically

public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 ImageView imageview = new ImageView(MainActivity.this);
 RelativeLayout relativelayout = (RelativeLayout)findViewById(R.id.relativeLayout);
 LinearLayout.LayoutParams params = new LinearLayout
 .LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

 // Add image path from drawable folder.
 imageview.setImageResource(R.drawable.demo_new_image);
 imageview.setLayoutParams(params); 
 relativelayout.addView(imageview); 

 }
}
