我有一个框架布局，我添加到它的图像，然后在文本，我想图像出现在屏幕的顶部。

 的FrameLayout FM =新的FrameLayout（本）;fm.addView（IM）;fm.addView（翅）; //鳍=文本视图的setContentView（FM）; 

解决方案

使用ImageView.setScaleType（）与ImageView.ScaleType.FIT_START的价值。

How can I dynamically set the gravity ?

Bitmap bmp;
im = new ImageView (this);
bmp=getbmp(img);
im.setImageBitmap(bmp);  

Now I would like to put the image in the top . Ho can I do this without android:gravity in main.xml ?

EDIT :

main.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:scrollbars="vertical"

    >
</ScrollView>

I have a frame layout and I add to it the image , and then the text and I would like the image to be on the top of the screen.

FrameLayout fm = new FrameLayout (this);
fm.addView(im);
fm.addView(fin); // fin = the text view
setContentView(fm);

Use ImageView.setScaleType() with ImageView.ScaleType.FIT_START as value.
