Greetings, I am a newcomer to StackOverflow and seeking assistance with a code snippet that replaces every underscore in a given string.
public class MainActivity extends AppCompatActivity {
private String result="";
private String textresult = "The red fox jumps over the lazy dog";
EditText text;
Button btn;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = findViewById(R.id.editText);
btn = findViewById(R.id.button_edittext);
final TextView tvtext = findViewById(R.id.result);
final String les = textresult.replaceAll("[a-z]", "_");
tvtext.setText(les);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v
String les1 = textresult.replaceAll("[a-z]", "_");
final String sampleText = text.getText().toString().trim();
int noOfBtns = sampleText.length();
int noOftext = les1.length();
final TextView[] btns = new TextView[noOfBtns];
for(int i=0;i<noOfBtns;i++)
{
btns[i] = new TextView(MainActivity.this);
btns[i].setText(sampleText.substring(i,i+1));
result = result+btns[i].getText().toString();
char[] c = result.toCharArray();
les1 = changeCharInPosition(i, c[i], les1);*/
tvtext.setText(les1);
}
}
});
}
The desired output would be as follows:
**T__ ___ ___ ____ ____ ___ ____ ___.**
The issue at hand involves targeting the first segment of text until the end and updating or replacing each character. For instance:
If a user inputs a word and updates it:
**user input: the red
display: the red ___ ____ ____ ___ ____ ___.**
If the user input includes incorrect letters:
**user input: the red fix
display: the red f*x ____ ____ ___ ____ ___.**
Your help with solving this problem is greatly appreciated. Thank you!
