Question

当用户想要添加新项目时，我调用了一个侦听器，监听器应该以这种形式显示带有2个EditText的AlertDialog

-AlertDialog Title
-AlertDialog Message
-TextView 1 above EditText1
-EditText1
-TextView 2 above EditText2
-EditText 2

两个按钮

-*Cancel* on the left
-*Add* on the right

我的代码是

OnClickListener addNewItemListener = new OnClickListener() {
        public void onClick(View v) {
            AlertDialog.Builder alert = new AlertDialog.Builder(
                    MyActivity.this);
            alert.setTitle(R.string.add_title);
            alert.setMessage(R.string.add_message);
                    final TextView t1 = new TextView(MyActivity.this);
                      t1.setText("Name");
            final EditText input1 = new EditText(MyActivity.this);
                    final TextView t2 = new TextView(MyActivity.this);
                    t2.setText("Value");
            final EditText input2 = new EditText(MyActivity.this);
                    alert.setView(t1);
            alert.setView(input1);
                    alert.setView(t2);
            alert.setView(input2);
            alert.setPositiveButton(R.string.cancel,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                        }
                    });
            alert.setNegativeButton(R.string.add,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                            try {
                                String name = input1.getText().toString();
                                double value = Double.parseDouble(input2
                                        .getText().toString());
                                addItem(name, value);
                            } catch (RuntimeException e) {
                                Alerts.DatiErrati(MyActivity.this);
                            }

                        }
                    });
            alert.show();
        }
    };

但不幸的是，我得到了一个只有一个EditText和两个按钮的AlertDialog，尽管我的原意是

我该如何解决这个问题？

您必须在LinearLayout中包含多个小部件，并使用setView进行最终布局

试试这个

OnClickListener addNewItemListener = new OnClickListener() {
            public void onClick(View v) {
                AlertDialog.Builder alert = new AlertDialog.Builder(
                        MyActivity.this);

                LinearLayout myLayout= new LinearLayout(MyActivity.this);
                myLayout.setOrientation(LinearLayout.VERTICAL);

                alert.setTitle(R.string.add_title);
                alert.setMessage(R.string.add_message);

                final TextView t1 = new TextView(MyActivity.this);
                t1.setText("Name");
                final EditText input1 = new EditText(MyActivity.this);
                final TextView t2 = new TextView(MyActivity.this);
                t2.setText("Value");
                final EditText input2 = new EditText(MyActivity.this);
                myLayout.addView(t1);
                myLayout.addView(input1);
                myLayout.addView(t2);
                myLayout.addView(input2);
                alert.setView(myLayout);
                alert.setPositiveButton(R.string.cancel,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                            }
                        });
                alert.setNegativeButton(R.string.add,
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                try {
                                    String name = input1.getText().toString();
                                    double value = Double.parseDouble(input2
                                            .getText().toString());
                                    addItem(name, value);
                                } catch (RuntimeException e) {
                                    Alerts.DatiErrati(MyActivity.this);
                                }

                            }
                        });
                alert.show();
            }
        };

您可以通过创建AlertDialog来显示custom dialog 例如这里是对话框 myalertdialog.xml

的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="+@id/myLayout
android:layout_width="match_parent"
android:layout_hight="match_parent"
android:orientation="vertical">
<TextView
android:id="+@id/myTextView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="TextView1"/>
<EditText
android:id="+@id=myeditText1'
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="+@id/myTextView2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="TextView2"/>
<EditText
android:id="+@id=myeditText2'
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>

然后在你的代码中

AlertDialog dialog;
AlertDialog.Builder builder=new AlertDialog.Builder(this);
LayoutInflator inflater=getLayoutInflator();
View dialogView=inflator.inflate(R.layougt.myalertdialog,(ViewGroup) getCurrentFocus());
dialogView.setView(dialogView);
alert.setPositiveButton(R.string.cancel,
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                        }
                    });
            alert.setNegativeButton(R.string.add,
                    new DialogInterface.OnClickListener() {


                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                        }
                    });
dialog=builder.create();
dialog.show();

为什么不为警报制作单独的xml布局...问题出在alert.setView（view）; setView（view）和addView（view）;

之间存在差异

带有2个textBox的AlertDialog无法正常工作
