我在TextView上的onClick按钮上遇到了几个问题。在我的代码中，我发出alertDialog以在有onClick事件时显示。但是，该应用程序正在关闭：
这是 ProfilePage.java

public class ProfilePage extends Activity {
//UI elements
TextView userMobile;
TextView userName;
Button updateButton;
String mobile;
String name;
PrefManager prefManager;
CircleImageView profile_image;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile_page);
userMobile = (TextView)findViewById(R.id.userMobile);
userName = (TextView)findViewById(R.id.userName);
updateButton = (Button)findViewById(R.id.updateButton);
profile_image = (CircleImageView)findViewById(R.id.profile_image);
prefManager = new PrefManager(getApplicationContext());
mobile = "+91 "+prefManager.getUserMobile();
name = prefManager.getUserName();
//Setting Up Name
if(name.equals(""))
{
userName.setText("Enter Your Name");
}
else
{
userName.setText(name);
}
//Setting Up Mobile Display Button
userMobile.setText(mobile);
userMobile.setEnabled(false);
}
public void editNameDialogue(View v)
{
//This shows the dialogue box which sets the text to the name textview
AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(getApplicationContext(), R.style.AlertDialogCustom));
LayoutInflater inflater = this.getLayoutInflater();
final View dialogue = inflater.inflate(R.layout.editing_name, null);
builder.setView(dialogue);
final EditText entered_name = (EditText)dialogue.findViewById(R.id.edited_name);
builder.setMessage("Entered Name");
builder.setPositiveButton("Set", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String newName = entered_name.getText().toString();
userName.setText(newName);
}
});
builder.setCancelable(false);
builder.create();
builder.show();
}
public void selectDP(View view)
{
//This will select DP and set it to the CircularImageView waiting to be transfered to the server.
Toast.makeText(ProfilePage.this, "Lets select DP", Toast.LENGTH_SHORT).show();
}
public void updateDetails(View view)
{
Toast.makeText(ProfilePage.this, "Nothing Right Now", Toast.LENGTH_SHORT).show();
//This will send everything to the server and preference manager.
//And send to the main activity
}
}
这是错误：

答案 0 :(得分：1)
Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
显然，R.style.AlertDialogCustom并非基于AppCompat主题。
