实际上我正在使用这部分代码但屏幕上没有显示
// add single button for find near me
Button myButton = new Button(this);
myButton.setText("Press me");
myButton.setBackgroundColor(Color.YELLOW);
RelativeLayout.LayoutParams buttonParams = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, elativeLayout.LayoutParams.WRAP_CONTENT);
buttonParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
buttonParams.addRule(RelativeLayout.CENTER_VERTICAL);
launchLayout.addView(myButton,buttonParams);
setContentView(launchLayout);
这是活动代码
