我正在尝试创建一个应用，用户可以在其中浏览一系列“菜单”以访问内容。
我创建了打开应用程序时出现的菜单
MainMenuActivity.java：
public class MainMenuActivity extends AppCompatActivity {
ListView listView;
ArrayAdapter<String> main_adapter;
String[] main_menu = {
"1 INTRO",
"2 HELP",
"3 AROUND THE WORLD"
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_menu_layout);
listView = (ListView) findViewById(R.id.main_list);
main_adapter = new ArrayAdapter<>(this, R.layout.main_list_custom_layout, R.id.main_list_item, main_menu);
listView.setAdapter(main_adapter);
}
public void openNewActivity(View view) {
EditText main_edit_text = (EditText) findViewById(R.id.main_edit_text);
String answer = main_edit_text.getText().toString().trim();
switch (answer) {
case "1": {
Intent intent = new Intent(this, IntroActivity.class);
startActivity(intent);
break;
}
case "2": {
Intent intent = new Intent(this, HelpActivity.class);
startActivity(intent);
break;
}
case "3": {
Intent intent = new Intent(this, AroundTheWorldActivity.class);
startActivity(intent);
break;
}
default: {
Intent intent = new Intent(getApplicationContext(), MainMenuActivity.class);
startActivity(intent);
break;
}
}
}
我创建了在第一个菜单上的EditText中键入“3”（案例3）时出现的菜单。
AroundTheWorldActivity.java：
public class AroundTheWorldActivity extends Activity {
ListView listView;
ArrayAdapter<String> around_the_world_adapter;
String[] around_the_world_menu = {
"1 OVERVIEW",
"2 RECEIVING"
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.around_the_world_layout);
listView = (ListView) findViewById(R.id.around_the_world_list);
around_the_world_adapter = new ArrayAdapter<>(this, R.layout.around_the_world_list_custom_layout, R.id.around_the_world_list_item, around_the_world_menu);
listView.setAdapter(around_the_world_adapter);
}
public void openNewActivity(View view) {
EditText around_the_world_edit_text = (EditText) findViewById(R.id.around_the_world_edit_text);
String answer = around_the_world_edit_text.getText().toString().trim();
switch (answer) {
case "1": {
Intent atwintent = new Intent(this, AroundTheWorldOverviewActivity.class);
startActivity(atwintent);
break;
}
case "2": {
Intent atwintent = new Intent(this, ReceivingActivity.class);
startActivity(atwintent);
break;
}
default: {
Intent atwintent = new Intent(getApplicationContext(), AroundTheWorldActivity.class);
startActivity(atwintent);
break;
}
}
}
我配置了在二级菜单中输入“1”（案例1）时打开的活动。
AroundTheWorldOverviewActivity.java：
public class AroundTheWorldOverviewActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.around_the_world_overview_layout);
}
}
around_the_world_overview_layout.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
>
<TextView
android:id="@+id/atw_overview_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-smallcaps"
android:gravity="center_horizontal"
android:padding="16dp"
android:text="Around The World Overview Text"
android:textAppearance="?android:textAppearanceLarge"
android:textColor="#ffffff"
/>
</RelativeLayout>
我能够浏览第二个菜单，但当我尝试访问第三个Activity时，该应用程序停止工作/崩溃。

OOPS ...我忘了在清单文件中添加一个活动 - 我感谢大家的帮助，我希望这并没有占用太多人的时间！ / p>
