安卓.view.InflateException : Binary XML file line #30: Error inflating class <unknown>

Question

我正在运行一个应用程序，它打开了一张 map ，上面有一个标记。

单击标记时，我试图打开一个对话框，其中包含一些字段。这是我的标记点击代码，

public boolean onMarkerClick(Marker arg0) {

    Log.d("", "here");
    View view = getLayoutInflater().inflate(R.layout.dialogview, null);
    view.setBackgroundColor(Color.LTGRAY);
    edtDate = (TextView) view.findViewById(R.id.edtDate);

    edtTime = (TextView) view.findViewById(R.id.edtTime);

    Dialog dialog = new Dialog(this,
            android.R.style.TextAppearance_Holo_WindowTitle);
    dialog.setTitle("Enter Details");
    LayoutParams lp = dialog.getWindow().getAttributes();
    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
    lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
    lp.gravity = Gravity.TOP | Gravity.LEFT;
    lp.dimAmount = 0;
    lp.flags = LayoutParams.FLAG_LAYOUT_NO_LIMITS
            | LayoutParams.FLAG_NOT_TOUCH_MODAL;

    Spinner ddlspinnerdata = (Spinner) view.findViewById(R.id.ddl);
    ddldata = ddlspinnerdata.getSelectedItem().toString();
    EditText edtname = (EditText) view.findViewById(R.id.personname);
    name = edtname.getText().toString();
    EditText edtLength = (EditText) view.findViewById(R.id.edtlength);
    length = edtLength.getText().toString();
    EditText edtWidth = (EditText) view.findViewById(R.id.edtwidth);
    width = edtWidth.getText().toString();
    EditText edtHeight = (EditText) view.findViewById(R.id.edtheight);
    height = edtHeight.getText().toString();
    date = edtDate.getText().toString();
    time = edtTime.getText().toString();

    dialog.setContentView(view);
    dialog.show();
         }

单击标记时出现此错误。我在 android 4.0.4 版本中运行这个应用程序。 这是我的日志，

这是我的 list 文件，

        android:value="MY_API_KEY" />

</manifest>

我在这里使用了一个 mapfragment。

 <fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
    android:clickable="true" />

在主要 Activity 中，我扩展了 FragmentActivity。这会导致异常吗？请澄清我。 请帮我弄清楚为什么会出现此错误。

感谢任何帮助。谢谢!!

Answer 1

为什么你要为请求焦点设置包装内容我认为这会给你异常(exception)

<requestFocus android:layout_width="wrap_content" />  

只需添加 <requestFocus/> 如果不尝试删除此行并检查某些样式是否给您 inflater 异常..

style="?android:attr/buttonStyleSmall"
