在XML中放比较固定的组件，在java代码中放变化比较多的复杂的组件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ll"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
</LinearLayout>
public class MainActivity extends Activity {
private ImageView iView[] = new ImageView[2];
private int ImageID[] = new int[] { R.drawable.img01,R.drawable.img02 };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout layout = (LinearLayout) findViewById(R.id.ll);
LayoutParams params = new LayoutParams(253,148);
for (int i = 0; i < ImageID.length; i++) {
iView[i] = new ImageView(this);
iView[i].setImageResource(ImageID[i]);
iView[i].setPadding(5,5,5);
iView[i].setLayoutParams(params);
layout.addView(iView[i]);
}
}
@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;
}
}
注意
1：java.lang.OutOfMemoryError错误，加载4张图片竟然还会说内存不足。。。
2 : setContentView(R.layout.activity_main);在findViewByID后面出现会导致得到的View是null
