我有这个Activity和一个用于构建listview的XML。从listview我只能设计一行,但现在我想改变完整背景的颜色意味着完整Activity的颜色。
public class MyActivity extends Activity implements
AdapterView.OnItemClickListener, View.OnClickListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ListView list = new ListView(this);
setContentView(list);
String[] items = { "Tom", "Sally", "Bill", "John", "Santiago",
"Isabella" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.review, R.id.textView1, items) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = super.getView(position, convertView, parent);
View text = row.findViewById(R.id.seemore);
text.setTag(position);
text.setOnClickListener(MyActivity.this);
View left = row.findViewById(R.id.imageView1);
left.setBackgroundResource(R.drawable.newapture);
left.setTag(position);
left.setOnClickListener(MyActivity.this);
return row;
}
};
,XML代码是:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#272727">
<ImageView
android:id="@+id/one"
android:layout_width="140dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/title"
android:layout_marginLeft="15dp"
android:layout_marginTop="14dp"
android:clickable="true"
/>
</RelativeLayout>
这里#272727改变了单行的颜色;我想改变背景。
答案 0 :(得分:1)
在活动布局xml中,使用 android:background 属性或 在 onCreate
中getWindow().setBackgroundDrawableResource(R.drawable.bg_img);
