Android button click text

Question

I have 4 buttons and 6 textviews. I want that when any button is clicked(let's say button 2) then, the text of button 2 should go in the first textview and when another button is clicked(let's say button 4) then the text of button 4 should go in second textview. I don't know what to do for that. I have written code for that please give me some condition for this`package com.aswdc_wordcross;

 import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class MainActivity extends AppCompatActivity implements View.OnClickListener { Button[] buttons = new Button[4]; TextView[] textViews = new TextView[6]; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); buttons[0] = (Button) findViewById(R.id.Button1); buttons[0].setOnClickListener(this); buttons[1] = (Button) findViewById(R.id.Button2); buttons[1].setOnClickListener(this); buttons[2] = (Button) findViewById(R.id.Button3); buttons[2].setOnClickListener(this); buttons[3] = (Button) findViewById(R.id.Button4); buttons[3].setOnClickListener(this); textViews[0] = (TextView) findViewById(R.id.txtview1); textViews[1] = (TextView) findViewById(R.id.txtview2); textViews[2] = (TextView) findViewById(R.id.txtview3); textViews[3] = (TextView) findViewById(R.id.txtview4); textViews[4] = (TextView) findViewById(R.id.txtview5); textViews[5] = (TextView) findViewById(R.id.txtview6); } @Override public void onClick(View v) { switch (v.getId()){ case R.id.Button1: break; case R.id.Button2: break; case R.id.Button3: break; case R.id.Button4: break; default: break; } } }`

Answer 1

You have 4 Buttons and 6 TextViews, so it is unclear what you want.
To set the text of a TextView you use its setText() method, like:

textViews[1].setText("something");

If you want the text of a Button to be displayed in a TextView:

textViews[1].setText(buttons[1].getText().toString());

So inside onClick() , implement the logic you want to apply at each case by using the above code like:

case R.id.Button2:
    textViews[X].setText(buttons[X].getText().toString());
    break;

Edit
If you want to set the text of the 1st TextView only, I guess this is textViews[0] ,
then you don't need the switch statement:

@Override
public void onClick(View v) {
    Button button = (Button) v;
    textViews[0].setText(button.getText().toString());
}

Edit2
If you want to set sequentially the text of the TextView s

@Override
public void onClick(View v) {
    Button button = (Button) v;
    for (int i = 0; i < textViews.length; i++) {
        if (textViews[i].getTag() == null) {
            textViews[i].setText(button.getText().toString());
            textViews[i].setTag("0");
            break;
        }
    }
}
