I have problem with edittext. I get text of Edit text and I want to say if text in edit text is equal to "a" do something but its not working

        button.setOnClickListener(new View.OnClickListener() {
        String adadrandom=editText.getText().toString();
        @Override
        public void onClick(View v) {
            if (adadrandom=="a"){
                System.out.println("yes");
            }else {
                System.out.println("no");
            }
        }
    });

also i use .equals() but again i see the same answer

CodePudding user response：

Write getText code inside the onClick method, and compare the values with equals method

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
 String adadrandom=editText.getText().toString();
        if (adadrandom.equals("a")){
            System.out.println("yes");
        }else {
            System.out.println("no");
        }
    }
});

Your IDE should be warning you not to used == but to use .equals

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String adadrandom = editText.getText().toString();
        //Use equals and by doing it on the a string you get 
        // null protection.
        if ("a".equals(adadradom)){
            System.out.println("yes");
        }else {
            System.out.println("no");
        }
    }
});

• .equals() method for content comparison

• == operators for reference comparison

      button.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          String adadrandom = editText.getText().toString();
          String displayData = adadrandom.equals("a") ? "Yes" : "No";
          System.out.println(displayData);
      }
  });

Place your getting text code in onClick method and replace == with .equals for ignore warning from IDE.

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        String adadrandom = editText.getText().toString();
        if (adadradom.contentEquals("a")){
            System.out.println("yes");
        }else {
            System.out.println("no");
        }
    }
});
