【问题描述】：

我想实现如下图所示的布局...示例 -spinner1 然后 text1 然后换行 spinner2 然后 text2 等等....一切都很好，我只是想要正确安排布局。我附上了我想要的图像，并且当前与代码一起显示。

我想要下图这样的布局

但目前它的显示如下-

Bookdetails.java

public class Bookdetails extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub

【解决方案1】：

如果您的数据是动态的，则使用 listView 和 spinner,textview 作为 xml 文件中的列表项。

同样从上一个活动到下一个活动，将数据作为可打包数组列表传递。这会有所帮助..

【讨论】：

数据和所有内容都是正确的，我在布局中需要帮助查看我正在获取的图像输出，并在我上传的图片中查看我想要的内容。
您的布局方向是垂直的，将其设置为水平将解决此问题。
为水平方向的不同座位创建不同的布局，并将所有这些添加到您的 xml 布局中。

【解决方案2】：

创建一个水平方向的Linearlayout，其中包含一个微调器和文本视图。

然后扩展该布局，而不是以编程方式创建 Spinner。

LinearLayout layout = layoutInflater.inflate(R.layout.your_layout, parent, false);
ll.addView(layout);

更新

if(seat1!=null){
        LinearLayout customLayout = (LinearLayout)layoutInflater.inflate(R.id.customLayout, ll, false)
        final TextView rowTextView = (TextView)customLayout.findViewById(R.id.textView)
        rowTextView.setText("Seat selected" + seat1);
        //<------------------------------------------------------------------------------>
        Spinner spinner = (Spinner)customLayout.findViewById(R.id.spinner);
        ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, spinnerArray);
        spinner.setAdapter(spinnerArrayAdapter);
        spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub

                Toast.makeText(getBaseContext(), spinnerArray.get(arg2).toString()+""+seat1, 
                        Toast.LENGTH_SHORT).show();
            }

            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });
        ll.addView(customLayout);
}

【讨论】：

只更新了第一个条件的代码，其余的你可以自己做。这很容易:)
它没有发生..它显示..类型不匹配：无法从 View 转换为 LinearLayout
我已经更新了代码。检查第二行，将其转换为 LinearLayout。

【解决方案3】：

对于每个

if(!(seat1==null)){
}

执行以下操作

        final TextView rowTextView = new TextView(this);
        rowTextView.setText("Seat selected" + seat1);

        //<------------------------------------------------------------------------------>
        Spinner spinner = new Spinner(this);
        ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, spinnerArray);
        spinner.setAdapter(spinnerArrayAdapter);
        spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                // TODO Auto-generated method stub

                Toast.makeText(getBaseContext(), spinnerArray.get(arg2).toString()+""+seat1, 
                        Toast.LENGTH_SHORT).show();
            }

            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

        LinearLayout linearLayout = new LinearLayout(this);
        linearLayout.setOrientation(LinearLayout.HORIZONTAL);
        linearLayout.addView(spinner);
        linearLayout.addView(rowTextView);
        ll.addView(linearLayout);
