Question

我在seekbarlist.xml的contentview中，需要获取seekbars.xml的布局。我需要将布局发送到CustomSeekBar构造函数。下面，您可以看到我尝试将内容视图设置为一个布局，抓住它，然后切换到另一个。这不起作用b / c我必须扩展listactivity并且布局必须有一个id为“list”的项目。 seekbars.xml没有“列表”，它拥有它是没有意义的。如何获得搜索栏的布局？

 public class ColorsActivity extends ListActivity {
/** Called when the activity is first created. */

//Array Adapter that will hold our ArrayList and display the items on the ListView
SeekBarAdaptor seekBarAdaptor;

//List that will  host our items and allow us to modify that array adapter
ArrayList<CustomSeekBar> seekBarArrayList=null;
// TextView myValueText;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.seekbars);
    LinearLayout myLayout = (LinearLayout)findViewById(R.layout.seekbars);

    setContentView(R.layout.seekbarlist);

    //Initialize ListView        
    ListView lstTest= getListView();


     //Initialize our ArrayList
    seekBarArrayList = new ArrayList<CustomSeekBar>();

    //Initialize our array adapter 
    seekBarAdaptor = new SeekBarAdaptor(ColorsActivity.this, R.layout.seekbars, seekBarArrayList);

    CustomSeekBar red = new CustomSeekBar(this, myLayout, "red", 1);
    //CustomSeekBar blue = new CustomSeekBar(this, "blue");
    //CustomSeekBar green = new CustomSeekBar(this, "green");

    //Set the above adapter as the adapter of choice for our list
    lstTest.setAdapter(seekBarAdaptor);

    seekBarArrayList.add(red);
    //seekBarArrayList.add(blue);
    //seekBarArrayList.add(green);

    Amarino.connect(this, "00:11:11:21:05:53");
 }

}

您需要使用LayoutInflater。

LayoutInflater.from(this).inflate(R.layout.seekbars, null);

您可以将null传递给ViewGroup参数。
