我想创建一个自定义对话框如下

我尝试了以下几点。

我创建了AlertDialog的子类。生成器,并使用自定义标题和自定义内容视图,并使用,但结果不是预期的。 另一个尝试是子类DialogFragment和自定义对话框内的onCreateDialog,但结果不是预期的。 然后我尝试使用一个普通的Dialog类。结果并不如预期的那样。

在这三种情况下,问题是当我忽略标题视图时,对话框的大小不是预期的,当我使用标题视图时,结果是在内容视图周围有一个粗边框(这看起来真的很糟糕)。现在我脑子里有两个问题……

我怎样才能做到呢?因为我已经尝试了很多事情,直接的回答会更受欢迎。 在android应用程序中显示错误或警告对话框的最佳方式是什么?

编辑 Android开发者文档建议我们应该使用对话片段或对话框向用户显示错误/警报消息。然而,他们一度说……

提示:如果你想要一个自定义对话框,你可以将一个Activity显示为一个对话框,而不是使用对话框api。简单地创建一个活动,并将其主题设置为manifest元素中的theme . holo . dialog。

这是什么意思?仅仅是为了显示错误消息而使用Activity不是太过分了吗??

public static void showCustomAlertDialog(Context context, String name,
            String id, String desc, String fromDate, String toDate,
            String resions) {
        final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                context);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.dialog, null);
        alertDialogBuilder.setView(view);
        alertDialogBuilder.setCancelable(false);
        final AlertDialog dialog = alertDialogBuilder.create();
        dialog.show();
        txt_empId = (TextView) view.findViewById(R.id.txt_dialog_empcode);
        txt_empName = (TextView) view.findViewById(R.id.txt_dialog_empname);
        txt_desc = (TextView) view.findViewById(R.id.txt_dialog_desc);
        txt_startDate = (TextView) view.findViewById(R.id.txt_dialog_startDate);
        txt_resions = (TextView) view.findViewById(R.id.txt_dialog_endDate);
        txt_empId.setTypeface(Utils.setLightTypeface(context));
        txt_empName.setTypeface(Utils.setLightTypeface(context));
        txt_desc.setTypeface(Utils.setLightTypeface(context));
        txt_startDate.setTypeface(Utils.setLightTypeface(context));
        txt_resions.setTypeface(Utils.setLightTypeface(context));

        txt_empId.setText(id);
        txt_empName.setText(name);

        txt_desc.setText(desc);
        txt_startDate.setText(fromDate + "\t to \t" + toDate);
        txt_resions.setText(resions);



        btn_accept = (Button) view.findViewById(R.id.btn_dialog_accept);
        btn_reject = (Button) view.findViewById(R.id.btn_dialog_reject);
        btn_cancel = (Button) view.findViewById(R.id.btn_dialog_cancel);
        btn_accept.setTypeface(Utils.setBoldTypeface(context));
        btn_reject.setTypeface(Utils.setBoldTypeface(context));
        btn_cancel.setTypeface(Utils.setBoldTypeface(context));

        btn_cancel.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                dialog.dismiss();

            }
        });

    }

创建自定义对话框的最简单方法:

Initialize and show dialog: ViewDialog alertDialoge = new ViewDialog(); alertDialoge.showDialog(getActivity(), "PUT DIALOG TITLE"); Create method: public class ViewDialog { public void showDialog(Activity activity, String msg) { final Dialog dialog = new Dialog(activity); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setCancelable(false); dialog.setContentView(R.layout.custom_dialoge_feedback); TextView text = (TextView) dialog.findViewById(R.id.text_dialog_feedback); text.setText(msg); Button okButton = (Button) dialog.findViewById(R.id.btn_dialog_feedback); Button cancleButton = (Button) dialog.findViewById(R.id.btn_dialog_cancle_feedback); final EditText edittext_tv = (EditText) dialog.findViewById(R.id.dialoge_alert_text_feedback); okButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Perfome Action } }); cancleButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { dialog.dismiss(); } }); dialog.show(); } } Create layout XML which you want or need.

另一种简单的方法。

步骤1)创建一个布局与适当的id。

步骤2)在任何你想要的地方使用以下代码。

LayoutInflater factory = LayoutInflater.from(this);
final View deleteDialogView = factory.inflate(R.layout.mylayout, null);
final AlertDialog deleteDialog = new AlertDialog.Builder(this).create();
deleteDialog.setView(deleteDialogView);
deleteDialogView.findViewById(R.id.yes).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        //your business logic 
        deleteDialog.dismiss();
    }
});
deleteDialogView.findViewById(R.id.no).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        deleteDialog.dismiss();    
    }
});

deleteDialog.show();

创建这样的警告对话框布局

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/btn"
        android:layout_width="match_parent"
        android:text="Custom Alert Dialog"
        android:layout_height="40dp">
    </Button>
</LinearLayout>

在Activity类上添加下面的代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    LayoutInflater inflate = LayoutInflater.from(this);
    alertView = inflate.inflate(R.layout.your_alert_layout, null);
    Button btn= (Button) alertView.findViewById(R.id.btn);

    showDialog();
  }

 public void showDialog(){
        Dialog alertDialog = new Dialog(RecognizeConceptsActivity.this);
        alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        alertDialog.setContentView(alertView);
        alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        alertDialog.show();
    }

创建自定义警报布局custom_aler_update.xml

然后将此代码复制到Activity:

AlertDialog basic_reg;
AlertDialog.Builder builder ;
builder = new AlertDialog.Builder(ct, R.style.AppCompatAlertDialogStyle);
LayoutInflater inflater = ((Activity) ct).getLayoutInflater();
View v = inflater.inflate(R.layout.custom_aler_update, null);
builder.setView(v);
builder.setCancelable(false);
builder.create();
basic_reg = builder.show();

复制此代码到样式:

<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/primaryTextColor</item>
    <item name="android:background">@color/white</item>
</style>
public static void showCustomAlertDialog(Context context, String name,
            String id, String desc, String fromDate, String toDate,
            String resions) {
        final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                context);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.dialog, null);
        alertDialogBuilder.setView(view);
        alertDialogBuilder.setCancelable(false);
        final AlertDialog dialog = alertDialogBuilder.create();
        dialog.show();
        txt_empId = (TextView) view.findViewById(R.id.txt_dialog_empcode);
        txt_empName = (TextView) view.findViewById(R.id.txt_dialog_empname);
        txt_desc = (TextView) view.findViewById(R.id.txt_dialog_desc);
        txt_startDate = (TextView) view.findViewById(R.id.txt_dialog_startDate);
        txt_resions = (TextView) view.findViewById(R.id.txt_dialog_endDate);
        txt_empId.setTypeface(Utils.setLightTypeface(context));
        txt_empName.setTypeface(Utils.setLightTypeface(context));
        txt_desc.setTypeface(Utils.setLightTypeface(context));
        txt_startDate.setTypeface(Utils.setLightTypeface(context));
        txt_resions.setTypeface(Utils.setLightTypeface(context));

        txt_empId.setText(id);
        txt_empName.setText(name);

        txt_desc.setText(desc);
        txt_startDate.setText(fromDate + "\t to \t" + toDate);
        txt_resions.setText(resions);



        btn_accept = (Button) view.findViewById(R.id.btn_dialog_accept);
        btn_reject = (Button) view.findViewById(R.id.btn_dialog_reject);
        btn_cancel = (Button) view.findViewById(R.id.btn_dialog_cancel);
        btn_accept.setTypeface(Utils.setBoldTypeface(context));
        btn_reject.setTypeface(Utils.setBoldTypeface(context));
        btn_cancel.setTypeface(Utils.setBoldTypeface(context));

        btn_cancel.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                dialog.dismiss();

            }
        });

    }
