Android中的对话框标题文字大小

Question

我正在开发一个Android应用程序,我想在其中设置对话框的文本大小.我使用以下代码和XML进行textview,但它只设置我的字段的大小.我也想设置标题的文字大小和颜色.

final CharSequence[] items = { "Fake Request", "Abusive Language","Indecent Approach","Unacceptable Attitude","Dangerous Behavior",};

           ArrayAdapter<CharSequence> itemsAdapter = new
           ArrayAdapter<CharSequence> (this,
                    R.layout.menu_items, items);
           AlertDialog.Builder   builder = new AlertDialog.Builder(this);
           builder.setTitle("My Title");
           builder.setIcon(R.drawable.icon);
           builder.setAdapter(itemsAdapter, new DialogInterface.OnClickListener()
           {
               public void onClick(DialogInterface dialog, int item) {
                          switch(item) {
                                  case 0:
                              //Mark as Beautiful
                                  break;
                               case 1:
                              //Mark as Beautiful
                                  break;
                            case 2: 
                                //Mark as Not a Portrait
                                  break;
                            case 3:
                              //Mark as Offensive
                                  break;
                           case 4:
                              //Mark as Spam
                                  break;
                           case 5:
                              //cancel
                           break;
                           }
               }
           }

               );
           builder.show();

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
       android:id="@android:id/text1"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:padding="10dip"
       android:layout_margin="5dip"
       android:gravity="center_vertical"
       android:textSize="5dip"
       android:textColor="@color/red_theme"
       android:typeface="normal"
       android:lineSpacingExtra="0dip"/>

Answer 1

使用自定义标题builder.setCustomTitle(textView)来设置标题的大小和颜色。

AlertDialog.Builder builder = new AlertDialog.Builder(context);
    TextView title = new TextView(context);
    title.setText("Title");
    title.setBackgroundResource(R.drawable.gradient);
    title.setPadding(10, 10, 10, 10);
    title.setGravity(Gravity.CENTER);
    title.setTextColor(getResources().getColor(R.color.green));
    title.setTextSize(22);
    builder.setCustomTitle(title);
    builder.setMessage("Message");
    builder.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
      @Override
      public void onClick(DialogInterface dialog, int which) {

    }
    });
    builder.setNegativeButton(R.string.no, null);
    AlertDialog dialog = builder.show();
    messageView = (TextView)dialog.findViewById(android.R.id.message);
    messageView.setGravity(Gravity.CENTER);
    dialog.show();

Answer 2

//Use this code
TextView myMsg = new TextView(this);
  myMsg.setText("Succesfully send!");
  myMsg.setGravity(Gravity.CENTER_HORIZONTAL);
  myMsg.setTextSize(20); 
  myMsg.setTextColor(Color.WHITE);
  //set custom title
        builder.setCustomTitle(myMsg);

Answer 3

如果要使用样式来完成所有操作：

<style name="MyDialog" parent="Base.Theme.AppCompat.Light.Dialog">
    <item name="android:windowTitleStyle">@style/DialogTitle</item>
</style>

<style name="DialogTitle" parent="TextAppearance.AppCompat.Large">
    <item name="android:textSize">18sp</item>
</style>

并像这样创建对话框

new AlertDialog.Builder(this, R.style.MyDialog);

Answer 4

为了达成这个：

1. 创建带有列表视图的 xml
2. 使用充气器充气该视图
3. 在AndroidBuilder中设置自定义视图
4. 使用自定义适配器来膨胀列表视图中的行。

做到以上几点你就可以实现你的定制了。
