Question

我想创建应用程序，当按下按钮时它会发出每个声音，每个按钮都包含在列表中（如图：enter link description here）所以我写了Im_SensShow.java，它扩展了ListActivity并拥有imsen_main.xml和imsen_row.xml它不起作用（强制关闭）请帮助

package com.android.proj; public class Im_SensShow extends ListActivity {
/** Called when the activity is first created. */
private DBAdapter db ;
private Cursor cursor ;
private static final int INSERT_ID = Menu.FIRST;
private static final int CHANGE_ID = Menu.FIRST + 1;
private static final int EDIT_ID   = Menu.FIRST + 2;
private static final int DELETE_ID = Menu.FIRST + 3;
//this will store situation id that is sent from main
private long thim_sens_id;
private ImageButton menuCarBtn;
TextView MyOutputText;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.imsen_main);
    MyOutputText = (TextView)findViewById(R.id.OutputText);
    db = new DBAdapter(this);
    setBinding();
    //setOnEvent();
    listData();
    registerForContextMenu(getListView());
}

private void setBinding(){
    //Binding Objects
    menuCarBtn = (ImageButton)findViewById(R.id.menuCarBtn);
}



private void listData(){
    db.open();
    Bundle dataBundle = Im_SensShow.this.getIntent().getExtras();
    thim_sens_id = dataBundle.getLong("THIMSENSID");
    cursor = db.getIm_Sen_List(thim_sens_id,1);
    MyOutputText.setText(thim_sens_id+"t");
    startManagingCursor(cursor);
    ListAdapter list = new SimpleCursorAdapter(
            this,
            R.layout.imsen_row,
            cursor,
            new String[] {DBAdapter.KEY_IM_SENS, DBAdapter.KEY_READING},
            new int[] {R.id.im_sens, R.id.reading});
    setListAdapter(list);
    db.close();

        menuCarBtn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {

Answer 1

您需要一个自定义适配器，您可以在其中拥有每个列表项的持有者，该列表项包含项目并允许它们被按下并拥有听众......等等。

查看此SO主题。

Android: ListView elements with multiple clickable buttons

在页面的第一个答案中，他有一个链接到他的博客，它可以很好地解释，并且还有一个指向android开发者页面的链接，在那里他们编写了一个自定义适配器。

按下ListActivity中每个列表中的按钮
