Android alertDialog的setContentView

如果有两个文本编辑，则在对话框中弹出该对话框。我想从提交时的文本编辑中获取信息，但不知道如何获取。我也不知道如何在普通对话框中执行提交或取消按钮（我知道您可以在带有“setNegativeButton”的alertDialog上执行）

那么，如何向常规对话框添加提交或取消？到目前为止，我的工作就是：

public void changeEmail(View v){

    Dialog dialog =  new Dialog(this);
    dialog.setContentView(R.layout.change_email_dialog);
    dialog.setTitle("Enter your new email");
    dialog.show();


}

我想我也在想，是否有人能快速解释一下，我将如何从对话框使用的布局中的两个文本编辑中获取信息？

创建自己的对话框

class YourDialog extends Dialog {

private TextView mTextView1, mTextView1;
private Button mButton1, mButton2;

public YourDialog(Context context) {
    super(context);


}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.change_email_dialog);

    // init your component from layout
    // and add listiner to them

}

}

你可以试试这个代码。我这样做是为了从对话框中获取一个值。使用文本和文本2的值

创建布局文件：custom.xml

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

    <TextView
        android:id="@+id/text1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFF" />

    <TextView
        android:id="@+id/text2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textColor="#FFF"/>

</RelativeLayout>

这里有一个关于堆栈溢出的问题，它提供了有关自定义对话框的信息。

我一直面临着完全相同的障碍

这是我在一项研究之后做的

activity_main.xml

myDialogFragment.java

public class myDialogFragment extends DialogFragment {
private Dialog alert;
MyDialogListener dialogListener;

public interface MyDialogListener {
    public void onDialogPositiveClick(DialogFragment dialog, String namel, String desc);
    public void onDialogNegativeClick(DialogFragment dialog);

    Log.w("onCreateDialog", "onCreateDialog: onCreateDialog invoked");
    AlertDialog.Builder alertDialogBuider = new AlertDialog.Builder(getActivity());

    alertDialogBuider.setTitle("Add a Title");

    LayoutInflater inflater = getActivity().getLayoutInflater();
    final View dialogView = inflater.inflate(R.layout.dialog_add_title_list, null);
    alertDialogBuider.setView(dialogView);
    alertDialogBuider.setPositiveButton("Add", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            EditText textChapterName = (EditText)dialogView.findViewById(R.id.edit_add_title);
            EditText textChapterDesc = (EditText)dialogView.findViewById(R.id.edit_add_desc);
            dialogListener.onDialogPositiveClick(myDialogFragment.this,
                    textChapterName.getText().toString(),
                    textChapterDesc.getText().toString());
        }
    });

    alertDialogBuider.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialogListener.onDialogNegativeClick(myDialogFragment.this);
        }
    });

    return alertDialogBuider.create();
}

@Override
public void onDismiss(DialogInterface dialog) {
    super.onDismiss(dialog);
    Toast.makeText(getActivity(), "Dialog: onDismiss", Toast.LENGTH_SHORT).show();
    }
}

使用支持库时，请确保导入的是android.support.v4.app.DialogFragment类，而不是android.app.DialogFragment
