不能使用按钮重复editText中的文本

Question

I have a simple activity in android with a button and an editText widget. I have referenced the resource for the button, created an instance variable for the button, and invoked the listener method on it.

When I run the application, the button prints to the edit text widget, but only once. I cannot continue to type "0000000", which is the ideal output that I want, rather than being stuck on "0".

The code I have used is:

public class MainActivity extends Activity implements OnClickListener {

Button btn1;
EditText text;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    btn1 = (Button) findViewById(R.id.btn0);

    // set an onclick listener to listen for when the buttons are clicked
    toe.setOnClickListener(this);

    text = (EditText) findViewById(R.id.editTextSimple);

}

@Override
public void onClick(View v) {
    text.setText(btn1.getText().toString());

}

@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;
}

}

Is there a method or a work around that I could implement in order to print more digits to the edit text view?

Thank you for your help

Answer 1

There is no need to reinvent the wheel here. You don't even have to use direct Strings.

Your onClick could simply be:

@Override
public void onClick(View v) {
    text.append(btn.getText());
}

Also, I don't know what "toe" is in

toe.setOnClickListener(this);

but you should be setting the clicklistener on btn1

Replace

text.setText(btn1.getText().toString());

with

String t=text.getText().toString();
text.setText(t+btn1.getText().toString())
