MainActivity.java

package com.example.android.menu;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;


public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void printToLogs(View view) {
        // Find first menu item TextView and print the text to the logs
 
        // Find second menu item TextView and print the text to the logs
 
        // Find third menu item TextView and print the text to the logs
 
    }
}

why this error

@mohamed-ismail-ops If you use androidX instead of android, you need changeimport android.support.v7.app.AppCompatActivity; to import androidx.appcompat.app.AppCompatActivity;

Anyone have an issue with this? Works for me...

`
public void printToLogs(View view) {
// Find first menu item TextView and print the text to the logs
TextView menuItemOne = findViewById(R.id.menu_item_1);
Log.i("First Menu Item", (String) menuItemOne.getText());

    // Find second menu item TextView and print the text to the logs
    TextView menuItemTwo = findViewById(R.id.menu_item_2);
    Log.i("Second Menu Item", (String) menuItemTwo.getText());

    // Find third menu item TextView and print the text to the logs
    TextView menuItemThree = findViewById(R.id.menu_item_3);
    Log.i("Third Menu Item", (String) menuItemThree.getText());

}`

public void printToLogs(View view) {
// Find first menu item TextView and print the text to the logs
TextView menu1 = (TextView) findViewById(R.id.menu_item_1);
Log.i("Menu App Log:",menu1.getText().toString());
// Find second menu item TextView and print the text to the logs
TextView menu2 = (TextView) findViewById(R.id.menu_item_2);
Log.i("Menu App Log:",menu2.getText().toString());
// Find third menu item TextView and print the text to the logs
TextView menu3 = (TextView) findViewById(R.id.menu_item_3);
Log.i("Menu App Log:",menu3.getText().toString());

}

thanks githup and udacity

package com.example.android.menu;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

TextView menu_item_1,menu_item_2,menu_item_3;
String text1,text2, text3;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    menu_item_1 = findViewById(R.id.menu_item_1);
    text1 = (String) menu_item_1.getText();
    
    menu_item_2 = findViewById(R.id.menu_item_2);
    text2 = (String) menu_item_2.getText();
    
    menu_item_3 = findViewById(R.id.menu_item_3);
    text3 = (String) menu_item_3.getText();

}

public void printToLogs(View view) {

    Log.v("MainActivity.java", text1);
    Log.v("MainActivity.java", text2);
    Log.v("MainActivity.java", text3);

}

}

Solution:

public void printToLogs(View view) {
// Find first menu item TextView and print the text to the logs
TextView textViewItem1 = (TextView) findViewById(R.id.menu_item_1);
String menuItem1 = textViewItem1.getText().toString();
Log.v("MainActivity", menuItem1);

// Find second menu item TextView and print the text to the logs
TextView textViewItem2 = (TextView) findViewById(R.id.menu_item_2);
String menuItem2 = textViewItem2.getText().toString();
Log.v("MainActivity", menuItem2);

// Find third menu item TextView and print the text to the logs
TextView textViewItem3 = (TextView) findViewById(R.id.menu_item_3);
String menuItem3 = textViewItem3.getText().toString();
Log.v("MainActivity", menuItem3);
}

why am i getting this error

@shubhams612 ,i m getting the same problem ,have u got it solved ?

I guess dimen.xml file if not there in resource/values/.
You can replace the error text with "16dp" temporarily
or you can create new dimen.xml file in resource/values/

Ok thanks 😊
