按钮重叠

按钮重叠

问题描述：

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....

</RelativeLayout>

This is the way buttons work when click on start button

发布您的布局xml文件 – arjun

发布布局文件...请现在回答... –

您正在隐藏该按钮，但您仍在使用OnClickListener进行侦听。尝试添加：

pauseStopWatch.setOnClickListener(null);

然后，当你让你的按钮可见：

pauseStopWatch.setOnClickListener(whatever);

请在查看布局文件和附加的图像后再回答... –

试试这个布局

在上面，在pause按钮将被设置为Gone。用户点击后可以看到start按钮
