@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);
}
@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/
public void printToLogs(View View){
TextView menu1 = (TextView) findViewById(R.id.menu_item_1);
String ahmed = (String) menu1.getText();
Log.i("MainActivity", ahmed);
TextView menu2 = (TextView) findViewById(R.id.menu_item_2);
ahmed = (String) menu2.getText();
Log.i("MainActivity", ahmed);
TextView menu3 = (TextView) findViewById(R.id.menu_item_3);
ahmed = (String) menu3.getText();
Log.i("MainActivity", ahmed);
}
package com.example.menu;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
Button button;
TextView menu_item_1, menu_item_2, menu_item_3;
@OverRide
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.menu_Btn);
menu_item_1 = findViewById(R.id.menu_item_1);
button.setOnClickListener(v -> {
printToLogs(menu_item_1);
});
}
public void printToLogs(View view) {
// Find first menu item TextView and print the text to the logs
Log.i("EnterpriseActivity.java", "Captin's Log, Stardate 43125.8." + "Mango sorbet");
// Find second menu item TextView and print the text to the logs
Log.i("EnterpriseActivity.java", "Captin's Log, Stardate 43125.8." + "Blueberry Pie");
// Find third menu item TextView and print the text to the logs
Log.i("EnterpriseActivity.java", "Captin's Log, Stardate 43125.8." + "Choolate lava cack");
}
}
why this error
