Android AlertDialog 列表中的文本下划线

Question

我有一个 AlertDialog，它在列表中显示不同的项目。现在我希望这些项目中的一些是斜体和一些下划线。这怎么可能？我真的需要创建一个自定义的 AlertDialog 吗？

我的代码：

    ArrayList<String> names = new ArrayList<String>();
    String[] splitted = response.split("\\|");
    for(String name:splitted) {
        names.add(name.split("\\+")[1]);
    }
    String[] items = new String[names.size()];
    items = names.toArray(items);
    AlertDialog.Builder builder = new AlertDialog.Builder(ChatActivity.this);
    builder.setTitle("Onlineliste");
    builder.setItems(items, null);
    AlertDialog alert = builder.create();
    alert.show();    

Answer 1

是的，您必须创建一个自定义警报对话框

对于下划线

textview.setPaintFlags(textview.getPaintFlags()|Paint.UNDERLINE_TEXT_FLAG)

斜体

textView.setTypeface(null, Typeface.ITALIC)

Answer 2

试试这个

 public class Common_SingleLine_Alert extends Dialog implements
        View.OnClickListener {

    Button okBtn;
    TextView messagetv;
    String messageStr;

    public Common_SingleLine_Alert(Context context, Spannable message) {
        super(context);
        // TODO Auto-generated constructor stub
        this.messageStr = message;

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.marker_info_window);

        okBtn = (Button) findViewById(R.id.okBtn);
        messagetv = (TextView) findViewById(R.id.address);

        messagetv.setText(messageStr);

        okBtn.setOnClickListener(this);
    }

    public void onClick(View v) {
        // TODO Auto-generated method stub

        dismiss();

    }

}

// xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:background="@color/white">

    <RelativeLayout
        android:id="@+id/relativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="30dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:background="@color/themeColor" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:text="@string/title"
            android:textColor="@color/white"
            android:textStyle="bold" />
    </RelativeLayout>

    <TextView
        android:id="@+id/address"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/relativeLayout1"
        android:layout_centerHorizontal="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="5dp"
        android:gravity="center_horizontal"
        android:text="TextView" />



        <Button
            android:id="@+id/okBtn"
            style="?android:attr/buttonStyleSmall"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_below="@+id/address"
            android:layout_centerHorizontal="true"
            android:background="@drawable/reverse_common_button_selection"
            android:text="@android:string/ok" 
            android:layout_marginTop="5dp"/>


</RelativeLayout>

// 怎么用

dialog = new Common_SingleLine_Alert(this, getResources()
                    .getString(Html.fromHtml("<i>Name</i>")));
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(true);
            dialog.setOnDismissListener(new Dialog.OnDismissListener() {

                public void onDismiss(DialogInterface d) {
                    // TODO Auto-generated method stub
                }
            });
            dialog.show();
