源代码如下：
//mainactivity代码
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button=(Button) this.findViewById(R.id.button);
button.setOnClickListener(new ButtonClickListener());
}
@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;
}
private final class ButtonClickListener implements View.OnClickListener{
@Override
public void onClick(View v) {
Intent intent=new Intent();
EditText editContent=(EditText) findViewById(R.id.mobile);
String num=editContent.getText().toString();
intent.setAction("android.intent.action.CALL");
intent.setData(Uri.parse("tel"+num));
MainActivity.this.startActivity(intent);
}
}
