在布局中点击会重定向到另一个布局

Question

我有一个布局，用于显示问题和选项，如果我点击除按钮以外的任何地方，都会跳转到默认布局。我想知道这是为什么。 我的类

package com.example.demo;

public class MainActivity extends Activity implements OnClickListener {

    DBHelper helper;
    SQLiteDatabase db;
    Button btnBegin,btnnext,btnredirect;
    int count = 0;
    int response = 0;

    View previouslySelectedItem = null;



    //Sub category Buttons
    Button btnaptitude5,btnaptitude4,btnaptitude3,btnaptitude2,btnaptitude1;

    String Question_ID,Title,TitleDescription,QuestionText,QuestionTemplate,QuestionImage;

    //String SubModuleQuestion_ID;

    TextView tvTitle,tvInstructions,tvQuestionText;

    RadioGroup rgtemplate4images;
    ImageView img;
     RelativeLayout aptitudesubcateg,temp4optimage, redirecttemplate;
    ListView listviewoptions;


    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.aptitude);

          aptitudesubcateg = (RelativeLayout) findViewById(R.id.aptitudesubcateg);
          temp4optimage = (RelativeLayout) findViewById(R.id.temp4optimage);

          temp4optimage.setClickable(false);

          redirecttemplate = (RelativeLayout) findViewById(R.id.redirecttemplate);

         // int position = 1;

不是重定向，而是替换对吧？ - Anoop M Maddasseri

是的，它不应该重定向...如果我在屏幕上点击空白处，它会替换为子类别页面... - Tushar Narang

正如您所看到的，我已经包含了一些<include>标签。 - Tushar Narang

好的...在我的端上运行良好...请尝试一下。 - Tushar Narang

你能在 onClick() 中检查一下是哪个 case 被调用了吗？我想要理解当你点击“除按钮以外的任何地方”时，哪个布局被替换了。 - Darpan

Answer 1

我曾经遇到过这样一个错误，即在片段B的空白处单击会引起底层片段A上的onClick事件。你的问题听起来与我的类似，所以我猜测你正在点击其中一个已包含但不可见布局的“隐形”按钮。

因此，请尝试将以下内容添加到父RelativeLayout中：

android:clickable="true"

- W3hri

Answer 2

原因：这是因为您之前的屏幕在子父级别上有触摸/点击监听器，当您的视图没有其中之一时，它会将该事件传递给父/超级视图。

解决方案有很多,

1）在当前活动/片段的父视图中添加行android:clickable="true"

2）在当前活动/片段的onCreate()中添加下面的代码

 root.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            return true;
        }
    });

3) 在您的视图的父布局中添加 android:onClick=temp，并在您的类中创建一个 temp(View v) 方法。

4) 如果它是一个片段，则在转换commit()之前添加此行 .addToBackStack(null)

- MKJParekh

Answer 3

尝试在onCreate()方法中调用除按钮外视图的setEnable(false)和/或setClickable(false)方法。但最重要的是，您应该检查id而不是直接检查视图：

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    int id = v.getId();
    switch(id){
        case R.id.btnaptitude1Id:
        ...
        break;
        case R.id.btn1:
        ...
    }

如果您不喜欢该标识符，至少应使用“equals（）”方法：

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    if(v.equals(btnBegin){
        ...
    }
    if(v.equals(btnaptitude1){
        ...
    }
    ...

看看这个是否有效。
