我一直试图在点击谷歌地图的标记时弹出一个自定义对话框。我使用此代码重写ItemizeOverlay Cals的onTap()方法

protected boolean onTap(int index) {
            AlertDialog.Builder builder;
            AlertDialog alertDialog;

            Context mContext = getApplicationContext();
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
            View layout = inflater.inflate(R.layout.custom_dialog,
                                           (ViewGroup) findViewById(R.id.layout_root));

            TextView textName = (TextView) layout.findViewById(R.id.text);
            textName.setText("Here is the Name");

            ImageView image = (ImageView) layout.findViewById(R.id.image);
            image.setImageResource(R.drawable.ic_launcher);


            builder = new AlertDialog.Builder(mContext);
            builder.setView(layout);

            alertDialog = builder.create();
            alertDialog.show();

            return super.onTap(index);
        }
下面是自定义对话框布局xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/layout_root"
          android:orientation="horizontal"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:padding="10dp"
          >
<ImageView android:id="@+id/image"
           android:layout_width="wrap_content"
           android:layout_height="fill_parent"
           android:layout_marginRight="10dp"
           />
<TextView android:id="@+id/text"
          android:layout_width="wrap_content"
          android:layout_height="fill_parent"
          android:textColor="#FFF"
          />
这正是上给出的示例

需要帮忙吗


谢谢

使用classname.this而不是getApplicationContext 如果它是一个简单的映射活动

如果它位于选项卡中,则使用getParent()

因为badtokenexception在其未采用正确的类引用时发生。

更改

    Context mContext = getApplicationContext();
    LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);

谢谢纽茨:)这正是问题所在。
    Context mContext = getApplicationContext();
    LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
    LayoutInflater inflater = (LayoutInflater) MyActivity.this.getSystemService(LAYOUT_INFLATER_SERVICE);
