如何在对话框中创建edittext框
如何在对话框中创建edittext框
提问于 2013-09-14 14:57:25
我正在尝试在一个对话框中创建一个编辑文本框来输入密码。当我这样做的时候，我不能这样做。我还是个初学者。在这方面请帮帮我。
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
我想成为
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();
}

使用活动上下文
替换这个
final EditText input = new EditText(this);通过
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); // uncomment this lineStack Overflow用户

我知道现在回答这个问题为时已晚，但对于正在搜索类似内容的其他人来说，这里是一个带有edittext的alertbox的简单代码
AlertDialog.Builder alert = new AlertDialog.Builder(this); 或
new AlertDialog.Builder(mContext, R.style.MyCustomDialogTheme);如果要更改对话框的主题，请执行以下操作。
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();Stack Overflow用户

简化版本
final EditText taskEditText = new EditText(this);
AlertDialog dialog = new AlertDialog.Builder(this)
.setTitle("Add a new task")
.setMessage("What do you want to do next?")
.setView(taskEditText)
.setPositiveButton("Add", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String task = String.valueOf(taskEditText.getText());
SQLiteDatabase db = mHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(TaskContract.TaskEntry.COL_TASK_TITLE, task);
db.insertWithOnConflict(TaskContract.TaskEntry.TABLE,
null,
values,
SQLiteDatabase.CONFLICT_REPLACE);
db.close();
updateUI();
}
})
.setNegativeButton("Cancel", null)
.create();
dialog.show();
