我一直在尝试解决这个问题一段时间，我确信有办法解决这个错误/问题，但我还没有找到。
我遇到的问题是，一旦我通过后退按钮或主页按钮退出应用程序，它就会关闭，然后重新打开我之前打开的一项活动。
一旦我按下其中一个按钮，我是否需要关闭我的活动，我将如何去做。
这是我的主要活动的代码，它打开了我的其他活动......

{

setContentView(R.layout.main);
ImageView p_btn = (ImageView) findViewById(R.id.imageView1);
p_btn.setOnTouchListener(new OnTouchListener()
{
public boolean onTouch(View view, MotionEvent event)
{
Intent myIntent2 = new Intent(view.getContext(), Cgt.class);
startActivity(myIntent2);
return false;
}
});
SeekBar skb = (SeekBar) findViewById(R.id.seekBar1);
try {
InputStream in = openFileInput("sa.txt");
if (in != null) {
InputStreamReader input = new InputStreamReader(in);
BufferedReader buffreader = new BufferedReader(input);
mla = "";
String line = new String();
line = buffreader.readLine();
mla += line;
Toast msg = Toast.makeText(getBaseContext(), "Loaded Saved Data", Toast.LENGTH_LONG);
msg.show();
in.close();
skb.setProgress(Integer.parseInt(mla.toString()));
}
else{}
} catch(Exception e){}
skb.setOnSeekBarChangeListener(new OnSeekBarChangeListener()
{
public void onProgressChanged(SeekBar event, int value, boolean sb)
{
vo = value;
}
public void onStartTrackingTouch(SeekBar event)
{
}
public void onStopTrackingTouch(SeekBar event)
{
try
{
OutputStreamWriter out = new OutputStreamWriter(openFileOutput("sa.txt", 0));
out.write(Integer.toString(vo));
out.close();
} catch (IOException e)
{
}
Toast msg = Toast.makeText(getBaseContext(), "Set Sensitivity to: " + Integer.toString(vo), Toast.LENGTH_LONG);
msg.show();
}
});
}
}
这是我要打开的活动的代码...
