我试图在输入密码的对话框中创建一个编辑文本框。
我作的时候，却不能作。我是一个初学者。
请帮帮我。
public class MainActivity extends Activity {
Button create, show, setting;
//String pass="admin";String password;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
create = (Button)findViewById(R.id.amcreate);
setting = (Button)findViewById(R.id.amsetting);
show = (Button)findViewById(R.id.amshow);
//input = (EditText)findViewById(R.id.this);
setting.setVisibility(View.INVISIBLE);
create.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent1 = new Intent(view.getContext(), Create.class);
startActivityForResult(myIntent1, 0);
}
});
show.setOnClickListener(new View.OnClickListener() {
//@SuppressWarnings("deprecation")
public void onClick(final View view) {
// Creating alert Dialog with one Button
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
//AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
// Setting Dialog Title
alertDialog.setTitle("PASSWORD");
// Setting Dialog Message
alertDialog.setMessage("Enter Password");
**final EditText input = new EditText(this);**
//alertDialog.setView(input);
// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.key);
// Setting Positive "Yes" Button
alertDialog.setPositiveButton("YES",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
// Write your code here to execute after dialog
Toast.makeText(getApplicationContext(),"Password Matched", Toast.LENGTH_SHORT).show();
Intent myIntent1 = new Intent(view.getContext(), Show.class);
startActivityForResult(myIntent1, 0);
}
});
// Setting Negative "NO" Button
alertDialog.setNegativeButton("NO",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Write your code here to execute after dialog
dialog.cancel();
}
});
// closed
// Showing Alert Message
alertDialog.show();
}
});
图像
我想得到as
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
alertDialog.setTitle("PASSWORD");
alertDialog.setMessage("Enter Password");
final EditText input = new EditText(MainActivity.this);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
input.setLayoutParams(lp);
alertDialog.setView(input);
alertDialog.setIcon(R.drawable.key);
alertDialog.setPositiveButton("YES",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
password = input.getText().toString();
if (password.compareTo("") == 0) {
if (pass.equals(password)) {
Toast.makeText(getApplicationContext(),
"Password Matched", Toast.LENGTH_SHORT).show();
Intent myIntent1 = new Intent(view.getContext(),
Show.class);
startActivityForResult(myIntent1, 0);
} else {
Toast.makeText(getApplicationContext(),
"Wrong Password!", Toast.LENGTH_SHORT).show();
}
}
}
});
alertDialog.setNegativeButton("NO",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
alertDialog.show();
}
});
我知道现在回答这个问题已经太迟了，但是对于其他正在搜索类似内容的人来说，这里有一个带有编辑文本的警报框的简单代码
AlertDialog.Builder alert = new AlertDialog.Builder(this);
or
new AlertDialog.Builder(mContext, R.style.MyCustomDialogTheme);
如果你想改变对话的主题。
final EditText edittext = new EditText(ActivityContext);
alert.setMessage("Enter Your Message");
alert.setTitle("Enter Your Title");
alert.setView(edittext);
alert.setPositiveButton("Yes Option", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//What ever you want to do with the value
Editable YouEditTextValue = edittext.getText();
//OR
String YouEditTextValue = edittext.getText().toString();
}
});
alert.setNegativeButton("No Option", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// what ever you want to do with No option.
}
});
alert.show();
最简单的是。
创建对话框的xml布局文件。添加任何你想要的视图
EditText, ListView, Spinner等。
膨胀这个视图并将其设置为AlertDialog
让我们首先从布局文件开始。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical">
<EditText
android:id="@+id/etComments"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:hint="Enter comments(Optional)"
android:inputType="textMultiLine"
android:lines="8"
android:maxLines="3"
android:minLines="6"
android:scrollbars="vertical" />
</LinearLayout>
final View view = layoutInflater.inflate(R.layout.xml_file_created_above, null);
AlertDialog alertDialog = new AlertDialog.Builder(requireContext()).create();
alertDialog.setTitle("Your Title Here");
alertDialog.setIcon("Icon id here");
alertDialog.setCancelable(false);
Constant.alertDialog.setMessage("Your Message Here");
final EditText etComments = (EditText) view.findViewById(R.id.etComments);
alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Cancel", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
alertDialog.dismiss()
}
});
alertDialog.setView(view);
alertDialog.show();
Wasim的回答把我带到了正确的方向，但我必须做出一些改变，才能让它适用于我目前的项目。
我在一个片段中使用这个函数，并在按钮单击时调用它。
fun showPostDialog(title: String) {
val alert = AlertDialog.Builder(activity)
val edittext = EditText(activity)
edittext.hint = "Enter Name"
edittext.maxLines = 1
var layout = activity?.let { FrameLayout(it) }
//set padding in parent layout
// layout.isPaddingRelative(45,15,45,0)
layout?.setPadding(45,15,45,0)
alert.setTitle(title)
layout?.addView(edittext)
alert.setView(layout)
alert.setPositiveButton(getString(R.string.label_save), DialogInterface.OnClickListener {
dialog, which ->
run {
val qName = edittext.text.toString()
showToast("Posted to leaderboard successfully")
view?.hideKeyboard()
}
})
alert.setNegativeButton(getString(R.string.label_cancel), DialogInterface.OnClickListener {
dialog, which ->
run {
dialog.dismiss()
}
})
alert.show()
}
fun View.hideKeyboard() {
val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
imm.hideSoftInputFromWindow(windowToken, 0)
}
fun showToast(message: String) {
Toast.makeText(activity, message, Toast.LENGTH_LONG).show()
}
我希望它能在不久的将来帮助到其他人。
编码快乐!
您可以尝试下面的代码
我创建了一个这样的方法
public void getReferDialog(OnSubmitBtnClick submitBtnClick) {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(activity);
final View customLayout = activity.getLayoutInflater().inflate(R.layout.dilog_refer_id, null);
alertDialog.setView(customLayout);
AlertDialog alert = alertDialog.create();
alert.setCancelable(false);
alert.setCanceledOnTouchOutside(false);
EditText editText = customLayout.findViewById(R.id.ed_refer_user_input);
Button submitBtn = customLayout.findViewById(R.id.btn_refer_submit);
TextView tvNo = customLayout.findViewById(R.id.tv_no_thanks);
TextView tvBody = customLayout.findViewById(R.id.tv_title_refer_dialog_body);
submitBtn.setOnClickListener(v -> {
String userText = editText.getText().toString();
if (!userText.equals("")) {
alert.dismiss();
submitBtnClick.onClick(userText);
}else {
tvBody.setTextColor(Color.RED);
}
});
tvNo.setOnClickListener(v -> {
alert.dismiss();
submitBtnClick.onClick("skip");
});
alert.show();
}
这是我的dilog_refer_id.xml文件
<?xml version="1.0" encoding="utf-8"?>

我的bg_edit_text_reference .xml(可绘制)文件
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/home_bg_extension"/>
<corners android:radius="15dp"/>
</shape>
为获取用户输入数据创建接口
public interface OnSubmitBtnClick {
void onClick(String referId);
}
最后都完成了，现在是时候调用onclick方法了
showPopupBtn.setOnClickListener(v -> {
getReferDialog(new OnSubmitBtnClick() {
@Override
public void onClick(String referId) {
Toast.makeText(LoginActivity.this, referId, Toast.LENGTH_SHORT).show();
}
});
});
谢谢你，快乐编码!!
