Question

我在底部有两个按钮，即listview结束后。

我正在使用自定义列表视图，该列表视图显示具有替代颜色的列表项。

如何为底部的两个按钮设置setOnClickListener？

public class PieMainActivity extends Activity  {

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

    mRes = getResources();
    new Random(new Date().getTime());

    solbtn = (Button)findViewById(R.id.solution);

    String recive ;

    Bundle b = getIntent().getExtras();
    final int piewrong=b.getInt("piewrong");
    final int pieright=b.getInt("pieright");
    final int pieunclick=b.getInt("pieunclick");

    setContentView(R.layout.piechart_result);


    recive = pieright+"/20";
    mPie.setUnit(recive);



    data1 = new ArrayList<String>();
    fillData() ;

    listtotal =getIntent().getStringArrayListExtra("listtotal");
    timeuse =getIntent().getStringArrayListExtra("timeused");

    adapter1 = new ListAdapter(this, data1, listtotal,timeuse);
    ListView lvMain = (ListView) findViewById(R.id.list);
    lvMain.setAdapter(adapter1);


    lvMain.setOnItemClickListener(new OnItemClickListener() {



        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            // TODO Auto-generated method stub
             int questionno = position+1;

                Bundle b = new Bundle();                
                b.putInt("questionno",questionno);
                b.putInt("piewrong",piewrong);
                b.putInt("pieright",pieright);
                b.putInt("pieunclick",pieunclick);
                Intent in=new Intent(PieMainActivity.this,Solution.class);
                in.putStringArrayListExtra("listtotal", (ArrayList<String>) listtotal);
                in.putStringArrayListExtra("timeused", (ArrayList<String>) timeuse);
                in.putExtras(b); 
                startActivity(in);
                finish();

        }
    });


}
void fillData() {
    for (int i = 1; i <= 20; i++) {
        data1.add("Question " + i);
    }
}
void fillcmp() {
    for (int i = 1; i <= 20; i++) {
        cmp.add("cmp " + i);
    }
}
}

BaseAdapter文件

public class ListAdapter extends BaseAdapter{
Context ctx;
LayoutInflater lInflater;
List<String> data1;
List<String> cmp;
List<String> timeused;

ListAdapter(Context context, List<String> data1 ,List<String> cmp ,List<String> timeused) {
    ctx = context;
    this.data1 = data1;
    this.cmp = cmp;
    this.timeused = timeused;

    ((TextView) view.findViewById(R.id.heading)).setText(data1.get(position));
    ((TextView) view.findViewById(R.id.duration)).setText(timeused.get(position));

Answer 1

所以这些按钮不是ListView的一部分？好吧，比你在onCreate做的那样：

solbtn = (Button)findViewById(R.id.solution);
solbth.setOnClickListener( toolbar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            yourMethod();
        }
    });

第二个按钮也是如此。

或者你可以让你的Activity实现View.OnClickListener，在这样做之后你可以像这样设置你的点击监听器：

//this two lines in your OnCreate
button1.setOnClickListener(this);
button2.setOnClickListener(this);

//somewhere later in the code

@Override
public void onClick(View v) {
    //do something
}

Answer 2

只需在onCrete()方法中添加clickListeners：

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

    .....

    solbtn = (Button) findViewById(R.id.home);
    homebtn = (Button) findViewById(R.id.solution);

    solbtn.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                // do stuff for solution button
            }
    });

    homebtn.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                // do stuff for home button
            }
    });

    .....
}
