@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LinearLayout layout=(LinearLayout)findViewById(R.id.layout);//获取个xml文件中定义的线性布局管理器
for(int i=0;i<imagePath.length;i++){//
img[i]=new ImageView(this);//创建一个ImageView组件
img[i].setImageResource(imagePath[i]);//为ImageView组件指定要显示的图片
img[i].setPadding(5, 5,5, 5);//设置ImageView组件的内边距
LayoutParams params=new LayoutParams(253,148);//设置图片的宽度和高度
img[i].setLayoutParams(params);//为ImageView组件设置布局参数
layout.addView(img[i]);//将ImageView组件添加到布局管理器中

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
效果如下图:
