我正在创建一个关于我们屏幕作为android中的弹出/对话框。我想在此对话框中添加一个按钮(OK或CANCEL)。我怎么能这样做?
这是我的布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:id="@+id/popup"
android:layout_height="wrap_content"
android:background="#E3C39D"
android:orientation="vertical"
android:padding="0dp">
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="About Us.."
android:layout_marginRight="16dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="16dp"
android:layout_marginBottom="8dp"
android:textSize="20dp"
android:textColor="#ffffff"
style="@style/TextShadow"/>
<View
android:id="@+id/SplitLine_hor1"
android:layout_width="match_parent"
android:layout_height= "1dp"
android:background="#000" />
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="16dp"
android:layout_marginLeft="16dp"
android:layout_marginTop="8dp"
android:layout_marginBottom="16dp"
android:text="Hello ! I want to put a button below with label 'OK' and Click on this OK button the popup should be close. Thank you !" />
</LinearLayout>
及以下是对话框
的功能public void AboutUsDialog(){
final AlertDialog.Builder alert;
alert = new AlertDialog.Builder(this);
LayoutInflater inflater = MainActivity.this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.activity_about_us, null);
alert.setView(dialogView);
alert.show();
alert.setPositiveButton("OK",null);
//alert.setInverseBackgroundForced(true);
}
我正在使用alert.setPositiveButton("OK",null);
或alert.setInverseBackgroundForced(true);
。但我没有在对话框中显示任何按钮。
当我触摸屏幕上的任何地方时,现在Dialog会关闭。我想通过OK按钮关闭弹出窗口。
提前致谢!

下面是我添加按钮的代码。
public void AboutUsDialog() {
final AlertDialog.Builder alert;
alert = new AlertDialog.Builder(this);
LayoutInflater inflater = MainActivity.this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.activity_about_us, null);
alert.setPositiveButton("OK", null); //This is my Solution to this question(adding OK button)
alert.setCancelable(false);
alert.setInverseBackgroundForced(true);
alert.setView(dialogView);
alert.show();
//alert.setInverseBackgroundForced(true);
}

你的按钮没有来,因为它应该是这样的
alert.setPositiveButton("OK",null);
alert.setView(dialogView);
alert.show();
而不是
alert.setView(dialogView);
alert.show();
alert.setPositiveButton("OK",null);
参考:
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setMessage("Are you sure,You wanted to make decision");
alertDialogBuilder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
Toast.makeText(MainActivity.this,"You clicked yes button",Toast.LENGTH_LONG).show();
}
});
alertDialogBuilder.setNegativeButton("No",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
试着让我知道
