分享程序员开发的那些事...

问题是由 MaterialDesignLibrary 。由于以下行对话框类：
@覆盖
保护无效的onCreate（捆绑savedInstanceState）{
requestWindowFeature（Window.FEATURE_NO_TITLE）;
....
}
在这里 requestWindowFeature 在调用后调用的setContentView 法活动。
要解决这个问题，您应该删除 requestWindowFeature（Window.FEATURE_NO_TITLE）; 从对话行类库
I am creating an application that consists of the simple and small registration form pop up in an alert dialog when we click a button. But it was showing an error called android.util.AndroidRuntimeException: requestFeature() must be called before adding content please make it solve
Here i also used the SQLite databse This is my activity
package com.example.androidmaterial;
import com.gc.materialdesign.views.ButtonFlat;

public class Sample extends Activity
{
ButtonFloat keyboard;
ButtonRectangle hide_keyboard;

EditText name;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample);
login_database_adapter = new LoginDataBaseAdapter(Sample.this);
login_database_adapter = login_database_adapter.open();
database = (ButtonFlat)findViewById(R.id.buttonflat);
database.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
Dialog dialog_signup = new Dialog(Sample.this,"Registration","Please Fill all the details");
dialog_signup.setContentView(R.layout.activity_signup);
final EditText username = (EditText)dialog_signup.findViewById(R.id.editText1);

final EditText confirmpass = (EditText)dialog_signup.findViewById(R.id.editText3);
final EditText name = (EditText)dialog_signup.findViewById(R.id.editText4);
final ButtonFlat register = (ButtonFlat)dialog_signup.findViewById(R.id.buttonflat);
register.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
String user_name = name.getText().toString();
String mqs_user_name = username.getText().toString();
String mqs_password = password.getText().toString();
String mqs_confirmpass = confirmpass.getText().toString();
if(mqs_user_name.equals("")||mqs_password.equals("")||mqs_confirmpass.equals(""))
{

}
if(mqs_password!=mqs_confirmpass)

}
else
{
login_database_adapter.insertEntry(mqs_user_name, mqs_password);
Toast.makeText(Sample.this, "Account Successfully created"+" "+user_name,Toast.LENGTH_LONG).show();
}
}
});
dialog_signup.show();
}
});
keyboard = (ButtonFloat)findViewById(R.id.buttonFloat);
hide_keyboard = (ButtonRectangle)findViewById(R.id.button_2);
hide_keyboard.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{try{
InputMethodManager imm_2 = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm_2.hideSoftInputFromInputMethod(getCurrentFocus().getWindowToken(),0);
}
catch(Exception e)
{
Toast.makeText(Sample.this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
});
keyboard.requestFocus();
keyboard.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Dialog dialog = new Dialog(Sample.this, "MedeQuip", "Hello...This is a sample dialog box check");
dialog.setOnAcceptButtonClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(Sample.this, "Click accept button", 1).show();
}
});
dialog.setOnCancelButtonClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(Sample.this, "Click cancel button", 1).show();
}
});
dialog.show();
}
});
}
@Override
protected void onDestroy() {
login_database_adapter.close();
super.onDestroy();
}
}
EDIT: her is the code i use
protected void onCreate(Bundle savedInstanceState){
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample);
login_database_adapter = new LoginDataBaseAdapter(Sample.this);
login_database_adapter = login_database_adapter.open();
}
This is my Logcat

Problem is caused by MaterialDesignLibrary.due to following line in Dialog class:
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
....
}
here requestWindowFeature is called after calling setContentView method in Activity.
To fix this issue you should remove requestWindowFeature(Window.FEATURE_NO_TITLE); line from Dialog class of library
