Question

我在Android studio 0.3.7中创建了最简单的程序。

public class test extends Activity implements View.OnClickListener {

TextView tt;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test);
    Button button = (Button) findViewById(R.id.button);
    tt = (TextView) findViewById(R.id.Sett);
    button.setOnClickListener(this);
}
@Override
public void onClick(View v) {
    switch(v.getId()){
        case R.id.button:
            tt.setText("Running");
            break;
}
}
}

但我的结果是我在logcat中发现错误。如何避免这个错误？我试图找到解决方案，但没有找到。另外我发现其他我的项目也有这个问题。

libcore.io.ErrnoException打开失败：Android Studio中的ENOENT（没有此类文件或目录）
