学习了半天的android，晒上我的第一个小小的android程序。OnClickListener()有点搞
package mth.android;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class AndroidActivity extends Activity implements View.OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//final View textDisplayer = this.findViewById(R.id.displayText);
//final TextView textDisplayer = (TextView) this.findViewById(R.id.displayText);
Button startActivityButton = (Button)this.findViewById(R.id.startAndroidActivity);
startActivityButton.setOnClickListener(this);
/*
Button startActivityButton = (Button)this.findViewById(R.id.startAndroidActivity);
// when class not implementing View.OnClickListener()
startActivityButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
// TODO Auto-generated method stub
display(textDisplayer);
}
});
*/
/*
View startActivityButton = this.findViewById(R.id.startAndroidActivity);
startActivityButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
// TODO Auto-generated method stub
textDisplayer.setText("Hello World");
textDisplayer.setBackgroundColor(0xFFFFFFFF);
}
});
*/
/*
TextView text = new TextView(this);
text.setText("Hello World");
setContentView(text);
*/
}
public void display(TextView tv)
{
tv.setText("Hello world");
tv.setBackgroundColor(0xFFFFFF00);
}
public void onClick(View v) {
// TODO Auto-generated method stub
final TextView textDisplayer = (TextView) this.findViewById(R.id.displayText);
textDisplayer.setText("Hello world");
textDisplayer.setBackgroundColor(BIND_AUTO_CREATE);
}
}
