我有一个程序，当点击图像按钮时，它应该从一个布局转到另一个布局。这是我的MainActivity代码：
public class MainActivity extends Activity {
private ImageButton abt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
abt = (ImageButton) findViewById(R.id.about);
abt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, AboutActivity.class);
startActivity(intent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是我的AboutActivity：
public class AboutActivity extends Activity{
private ImageButton aboutbk;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about);
aboutbk = (ImageButton) findViewById(R.id.aboutBack);
aboutbk.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
我的activity_main xml布局文件:(我已经为我的实际程序完成了布局，但现在我只是使用了我的关于图像按钮）

这很简单，但不起作用？我已经在我的AndroidManifest上宣布了第二个活动，但它仍然不起作用？请帮帮我，我一直在谷歌搜索寻找解决方案，但我似乎找不到一个。
