错误SeekBar Android

标签： android onchange seekbar

我的程序有问题...我想做一个简单的搜索栏，在更改吐司时会显示其值。

这是我的代码：

SeekBar seek = (SeekBar) findViewById(R.id.seekBar1);

seek.setOnSeekBarChangeListener( new OnSeekBarChangeListener() {

 public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
      Toast.makeText(getApplicationContext(), progress, Toast.LENGTH_SHORT).show();
 }

  public void onStartTrackingTouch(SeekBar arg0) {

  }

  public void onStopTrackingTouch(SeekBar arg0) {

  }
  });

这是我的错误（日志）：

答案 0 :(得分：2)

不要将progress变量直接传递给makeText(Context, int, int)，因为该版本的方法需要资源ID（与R自动生成的文件中的条目对应的int值）。改为通过String.valueOf(progress)，将其转换为String并致电makeText(Context, String, int)。换句话说，替换它：

Toast.makeText(getApplicationContext(), progress, Toast.LENGTH_SHORT).show();

用这个：

 Toast.makeText(getApplicationContext(), String.valueOf(progress), Toast.LENGTH_SHORT).show();
