我想修改AlertDialog.Builder的标题和正文风格 儿子我使用setCustomTitle和setView来达到这个目的 以下是简化代码:
private AlertDialog dialog;
public void Showdialog() {
LayoutInflater inflaterTitle = getLayoutInflater();
View TitleView = inflaterTitle.inflate(layout, (ViewGroup)findViewById(id));
TextView Title = (TextView)TitleView.findViewById(id);
Title.setText("Title");
LayoutInflater inflaterBody = getLayoutInflater();
View BodyView = inflaterBody.inflate(layout, (ViewGroup)findViewById(id));
TextView Body = (TextView)BodyView.findViewById(id);
Body.setText("Body");
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCustomTitle(TitleView);
builder.setView(BodyView);
dialog = builder.create();
dialog.show();
}
TitleView和BodyView with bule background。
显示对话框如下。
有2个黑色
我该如何删除它?

而不是那样,如果你想为对话框设置自定义布局,那么请使用下面的代码。
final Dialog dialog = new Dialog(SplashActivity.this,R.style.CustomDialogTheme);
dialog.getWindow();
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.internet_dialog);
dialog.setCancelable(false);
Button retryBtn = (Button) dialog.findViewById(R.id.retryBtn);
Button cancel = (Button) dialog.findViewById(R.id.cancelBtn);
retryBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
dialog.dismiss();
checkForInternetAndNextFlow();
}
});
cancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
dialog.dismiss();
finish();
}
});
dialog.show();
值中的styles.xml包含:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="CustomDialogTheme" parent="@android:style/Theme.Dialog">
<item name="android:windowIsFloating">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
<item name="android:fitsSystemWindows">true</item>
<!-- <item name="android:colorBackgroundCacheHint">#00000000</item>
<item name="android:background">#00000000</item> -->
</style>
这对你有很大的帮助。您可以根据需要设置任何视图。

尝试使用自定义布局的Dialog,如下所示......
<强> RES /布局/ main.xml中:强>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
