自定义 ListView 菜单的基础 Activity

Question

我是 Android 编程新手。我正在开发一个具有多项活动的应用程序。我用 ListView 创建了一个自定义菜单。我想将此菜单放在基础 activity 中，以便在所有活动中都可用。我应该怎么做？

到目前为止，我有这样的事情：

这是用于切换菜单的按钮

menuToggelIcon.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
    // Hide layouts if VISIBLE
    if(menuLayout.getVisibility() == View.VISIBLE)
    {
      menuLayout.setVisibility(View.GONE);
    }
    // Show layouts if they're not VISIBLE
    else
    {
      menuLayout.setVisibility(View.VISIBLE);
    }
  }
});

这是菜单

menuListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    String name = menuArray[position];

    Context context = getApplicationContext();

    switch (name) {
      case "CASE1":
        Intent case1Intent = new Intent(context, Activity1.class);
        startActivity(case1Intent);
        break;
      case "CASE2":
        Intent case2Intent = new Intent(context, Activity2.class);
        startActivity(case2Intent);
        break;
      case "CASE3":
        Intent case3Intent = new Intent(context, Activity3.class);
        startActivity(case3Intent);
        break;
      case "CASE4":
        Intent case4Intent = new Intent(context, Activity4.class);
        startActivity(case4Intent);
        break;
      case "CASE5":
        Intent case5Intent = new Intent(context, Activity5.class);
        startActivity(case5Intent);
        break;
      case "CASE6":
        Intent case6Intent = new Intent(context, Activity6.class);
        startActivity(case6Intent);
        break;
      case "CASE7":
        Intent case7Intent = new Intent(context, Activity7.class);
        startActivity(case7Intent);
        break;
      default:
        break;
    }
  }
});

Android custom menu

Answer 1

制作一个 BaseActivity class 并且所有 activity 由 BasyActivity class 扩展。 BaseActivity class 定义显示所有屏幕的主要内容，如菜单和其他内容。例如

public class BaseActivity extends AppCompatActivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.manu_file_name, menu);


    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.icon) {
        Toast.makeText(getApplicationContext(), "Hello World", 0).show();
    }
    return super.onOptionsItemSelected(item);
}

}

并且这个 activity 扩展了所有其他 activity。
