Replace substring from inputText

fikriakhdi · Mar 25, 2014

Hello all

i'm newbie
i just want to ask..
how to replace substring from textinput/input text?
this is my code
public void ngeji(EditText editText){
EditText editteks = (EditText) findViewById(R.id.editText1);
String str = editteks.getText().toString();
if(str!= null){
str.toUpperCase();
str.replaceAll("U", "OO");
str.replaceAll("C", "TJ");
str.replaceAll("F", "EV");
str.replaceAll("ES", "X");
str.replaceAll("EKS", "X");
editText.setText(str);}
}
public void normalin(EditText editText){
EditText editteks = (EditText) findViewById(R.id.editText2);
String str = editteks.getText().toString();
if(str!=null){
str.toLowerCase();
str.replaceAll("oo", "u");
str.replaceAll("tj", "c");
str.replaceAll("ev", "f");
str.replaceAll("x", "eks");
str.replaceAll("y", "i");
str.replaceAll("q", "k");
editText.setText(str);
}
}

what's wrong with the code?

btw i just wanna make translator...its like ticky word translator
for example
i = OO
j = DJ
and Uppercase all
when i type : juanda
so... the result is DJOOANDA

i'll wait for your reply
thanks

Both .toUpperCase() and .replaceAll() return a string - they do not affect the string that you run them against. So this will do nothing...

Code:

str.toUpperCase();
str.replaceAll("U", "OO");
str.replaceAll("C", "TJ");
str.replaceAll("F", "EV");
str.replaceAll("ES", "X");
str.replaceAll("EKS", "X");

This is what you want...

Code:

str = str.toUpperCase();
str = str.replaceAll("U", "OO");
str = str.replaceAll("C", "TJ");
str = str.replaceAll("F", "EV");
str = str.replaceAll("ES", "X");
str = str.replaceAll("EKS", "X");

Thanks for the solution

Code:

package com.example.qdjytranslator;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.EditText;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}
	public void ngeji(EditText editText){
		EditText editteks = (EditText) findViewById(R.id.editText1);
		String str = editteks.getText().toString();
		if(str!= null){
			str = str.toUpperCase();
			str = str.replace("U", "OO");
			str = str.replace("C", "TJ");
			str = str.replace("F", "EV");
			str = str.replace("ES", "X");
			str = str.replace("EKS", "X");
			editText.setText(str);
			}
	}
	public void normalin(EditText editText){
		EditText editteks = (EditText) findViewById(R.id.editText2);
		String str = editteks.getText().toString();
		if(str!=null){
			str = str.toLowerCase();
			str = str.replace("oo", "u");
			str = str.replace("tj", "c");
			str = str.replace("ev", "f");
			str = str.replace("x", "eks");
			editText.setText(str);
		}
	}
	
	public void onTerminate()
	{
		super.onDestroy();
		this.finish();
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

Where do you call these methods ?

Code:

ngeji(EditText editText)
normalin(EditText editText)

^^ This, and what errors do you have?

Why are you using an edittext as an input for both functions when you are not using it.just leave brackets empty
public void function()
{
}
