Android 在片段上调用onClickListener的正确方法

android view android-fragments

Android 在片段上调用onClickListener的正确方法,android,view,android-fragments,onclick,onclicklistener,Android,View,Android Fragments,Onclick,Onclicklistener,我正在开发一个包含自定义拨号程序片段的应用程序。此片段的功能应与股票拨号器相同。当我按下一个按钮时，这个数字就会出现在editText窗口中，就这么简单 但是，编辑文本上没有显示数字。我第一次尝试使用活动而不是片段，效果很好。现在，我被迫将活动更改为片段，并根据片段eviroment修改代码，但此功能不起作用 这是PhoneView片段： public class PhoneView extends Fragment implements OnTabChangeListener, OnClick

我正在开发一个包含自定义拨号程序片段的应用程序。此片段的功能应与股票拨号器相同。当我按下一个按钮时，这个数字就会出现在editText窗口中，就这么简单

但是，编辑文本上没有显示数字。我第一次尝试使用活动而不是片段，效果很好。现在，我被迫将活动更改为片段，并根据片段eviroment修改代码，但此功能不起作用

这是
PhoneView
片段：

public class PhoneView extends Fragment implements OnTabChangeListener, OnClickListener {

    ImageButton dialBtn;
    ImageButton clearBtn;
    EditText numTxt;
    ImageButton button1;
    ImageButton button2;
    ImageButton button3;
    ImageButton button4;
    ImageButton button5;
    ImageButton button6;
    ImageButton button7;
    ImageButton button8;
    ImageButton button9;
    ImageButton button0;
    ImageButton buttonstar;
    ImageButton buttonpound;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View mRoot = inflater.inflate(R.layout.phone_view, null);

        dialBtn = (ImageButton) mRoot.findViewById(R.id.dialButton);
        clearBtn = (ImageButton) mRoot.findViewById(R.id.deleteButton);
        numTxt = (EditText) mRoot.findViewById(R.id.digits);
        button1 = (ImageButton) mRoot.findViewById(R.id.one);
        button2 = (ImageButton) mRoot.findViewById(R.id.two);
        button3 = (ImageButton) mRoot.findViewById(R.id.three);
        button4 = (ImageButton) mRoot.findViewById(R.id.four);
        button5 = (ImageButton) mRoot.findViewById(R.id.five);
        button6 = (ImageButton) mRoot.findViewById(R.id.six);
        button7 = (ImageButton) mRoot.findViewById(R.id.seven);
        button8 = (ImageButton) mRoot.findViewById(R.id.eight);
        button9 = (ImageButton) mRoot.findViewById(R.id.nine);
        button0 = (ImageButton) mRoot.findViewById(R.id.zero);
        buttonstar = (ImageButton) mRoot.findViewById(R.id.star);
        buttonpound = (ImageButton) mRoot.findViewById(R.id.pound);

        dialBtn.setOnClickListener(this);
        clearBtn.setOnClickListener(this);
        button1.setOnClickListener(this);
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);
        button4.setOnClickListener(this);

        button8.setOnClickListener(this);
        button9.setOnClickListener(this);
        button0.setOnClickListener(this);
        buttonstar.setOnClickListener(this);
        buttonpound.setOnClickListener(this);

        return mRoot;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()){
            case R.id.dialButton:
                startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + numTxt.getText())));
                break;
            case R.id.deleteButton:
                String contents = numTxt.getText().toString();
                if (contents.length() > 0) {
                    numTxt.setText(contents.substring(0, contents.length()-1));
                }
                break;
            case R.id.one:
                numTxt.setText(numTxt.getText()+"1");
                break;
            case R.id.two:
                numTxt.setText(numTxt.getText()+"2");
                break;
            case R.id.three:
                numTxt.setText(numTxt.getText()+"3");
                break;
            case R.id.four:
                numTxt.setText(numTxt.getText()+"4");
                break;
            case R.id.five:
                numTxt.setText(numTxt.getText()+"5");
                break;
            case R.id.six:
                numTxt.setText(numTxt.getText()+"6");
                break;
            case R.id.seven:
                numTxt.setText(numTxt.getText()+"7");
                break;
            case R.id.eight:
                numTxt.setText(numTxt.getText()+"8");
                break;
            case R.id.nine:
                numTxt.setText(numTxt.getText()+"9");
                break;
            case R.id.zero:
                numTxt.setText(numTxt.getText()+"0");
                break;
            case R.id.star:
                numTxt.setText(numTxt.getText()+"*");
                break;
            case R.id.pound:
                numTxt.setText(numTxt.getText()+"#");
                break;
        }
比如说，拨号键起作用，但不起作用的是在编辑文本上显示按下的数字。这可能与片段的任何限制或特殊功能有关吗

更新->在上面和xml后面添加了更多代码

声明
numText
为类成员。你有

EditText numTxt = (EditText) mRoot.findViewById(R.id.digits);
// local to onCreateView
改为

EditText numTxt;
@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View mRoot = inflater.inflate(R.layout.phone_view, null);

        ImageButton dialBtn = (ImageButton) mRoot.findViewById(R.id.dialButton);
        ImageButton clearBtn = (ImageButton) mRoot.findViewById(R.id.deleteButton);
        numTxt = (EditText) mRoot.findViewById(R.id.digits);
编辑：更新后的问题

正如我在评论中所说的，我认为发布的代码没有任何问题

既然你说不能将文本设置为editText，我就运行了你的代码。出于测试目的，我将启动器图标设置为背景，设置为
ImageButton
。为了测试的目的，我修改了ui

但逻辑和你用的一样

以这种方式更新，但仍然不起作用。使用带有片段的editText有什么问题吗？我投入了一点资金，似乎用片段动态更新edittext会导致此类问题。。但是，如何选择它？@masmic_87检查您的编辑文本是否正确初始化。不是碎片的错，我正试图理解为什么不适合我，但我快疯了！谢谢你的帮助。我会再投资一点，看看是否能找到原因。如果我发现了什么，我会发布一个新的问题你不会相信的。。。我发现发生了什么事！文本与背景颜色相同。。。这就是为什么我看不到。。。LOL@masmic_87哇！这就是为什么如果我改变用户界面，它对我有效。下次将文本设置为edittext in xml，并在图形编辑器中检查其是否可见。你昨天发布了相同的问题是的，我一直在寻找解决方案，但没有。。。我试图改变一些事情，这就是我提出新问题的方式。声明与我昨天的方式有些不同。@masmic_87如果重复，您可以随时编辑您的问题。你没有得到一个解决方案你可以提供一个赏金我会删除昨天的问题，我认为这有更多的代码，问题更清楚
