enter image description here我试图改变发布活动，但遇到一个空白屏幕，说＆＃34;方法＆＃34; （从@new_name字符串中提取）。
  我试图更改它，以便MainMenu将启动而不是activity_main 表现

我已经改变了实际的NewActivity，这是我现在想要启动的活动，我想让它显示mainmenu.xml

NewActivity：

由于某种原因，LogCat根本不会显示任何内容。我会看看我是否能找出原因并随之更新。

答案 0 :(得分：1)

您需要更改此

 protected void onCreate11(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainmenu);
    }

到

Button button,button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainmenu);
    button = (Button) findViewById(R.id.button9);
    button1 = (Button) findViewById(R.id.button1);
    addListenerOnButtonNews();     
    addListenerOnButtonGPS() 
    }

也改为

public void addListenerOnButtonNews() {
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
    Intent intent = new Intent(getApplicationContext(), NewActivity.class);
    startActivity(intent);   

}
});
}

public void addListenerOnButtonGPS() {
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);   

}});  
}
