我做了一个秒表，使用四个按钮的天文钟，但是当我使用可见性模式，使停止和暂停按钮出现它们重叠....请说明原因...下面是代码.....按钮重叠
假设在相对布局按钮布局文件...
public class StopWatchFragment extends Fragment {
Chronometer chronometer;
Button startStopWatch;
Button stopStopWatch;
Button resetStopWatch;
Button pauseStopWatch;
Button resumeStopWatch;
private long lastPause;
//RelativeLayout relativeLayout;
private int check = 0;
public StopWatchFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.stopwatch_layout,container,false);
chronometer = (Chronometer) rootView.findViewById(R.id.stopwatch);
startStopWatch = (Button) rootView.findViewById(R.id.startStopWatch);
stopStopWatch = (Button) rootView.findViewById(R.id.stopStopWatch);
resetStopWatch = (Button) rootView.findViewById(R.id.resetStopWatch);
pauseStopWatch = (Button) rootView.findViewById(R.id.pauseStopWatch);
resumeStopWatch = (Button) rootView.findViewById(R.id.resumeStopWatch);
relativeLayout = (RelativeLayout) rootView.findViewById(R.id.parentRelativeLayout);
pauseStopWatch.setVisibility(View.GONE);
//final RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(relativeLayout.getLayoutParams());
startStopWatch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.start();
startStopWatch.setVisibility(View.GONE);
pauseStopWatch.setVisibility(View.VISIBLE);
if(check == 1){
resumeStopWatch.setClickable(true);
}
else{
resumeStopWatch.setClickable(false);
}
//params.setMargins(16,16,16,16);
//pauseStopWatch.setLayoutParams(params);
}
});
pauseStopWatch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
check = 1;
lastPause = SystemClock.elapsedRealtime();
chronometer.stop();
}
});
resumeStopWatch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
chronometer.setBase(chronometer.getBase() + SystemClock.elapsedRealtime() - lastPause);
chronometer.start();
resumeStopWatch.setClickable(false);
}
});
stopStopWatch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
chronometer.stop();
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
resumeStopWatch.setClickable(false);
}
});
resetStopWatch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
chronometer.setBase(SystemClock.elapsedRealtime());
chronometer.stop();
resumeStopWatch.setClickable(false);
startStopWatch.setVisibility(View.VISIBLE);
pauseStopWatch.setVisibility(View.GONE);
}
});
return rootView;
}
}
这是布局文件请参阅此....
