如何在所有活动中显示菜单和标题？

Question

我创建了三个活动浏览/交易和包。 我已经使用抽屉布局创建了菜单。 我想在每个活动屏幕上看到我的菜单图标。 我为菜单项创建了一个基本活动，并将其扩展到所有活动。 我在下面附加我的家庭活动代码，基本活动代码并浏览活动代码

在此处输入图片说明

这是探索活动代码

package com.example.windows81.travelspoc;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class ExploreActivity extends BaseActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_explore);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    //getMenuInflater().inflate(R.menu.menu_second, menu);  <- remove this
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    return super.onOptionsItemSelected(item);
}
}

这是我的家庭活动代码

    viewPager.setAdapter(viewPagerAdapter);

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new MyTimerTask(), 2000, 4000);

    dotscount = viewPagerAdapter.getCount();
    dots = new ImageView[dotscount];

    for (int i = 0; i < dotscount; i++){
        dots[i] = new ImageView(this);


dots[i].setImageDrawable(ContextCompat.getDrawable(getApplicationContext(),

        LinearLayout.LayoutParams params = new

    }

dots[0].setImageDrawable(ContextCompat.getDrawable(getApplicationContext(),

    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int 
positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {

            for (int i = 0; i < dotscount; i++){

            }

        }

        @Override

@Override

    }
    switch (item.getItemId()) {
        case R.id.explore:
            // do what you want here
            myMethod();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

public class MyTimerTask extends TimerTask{

    @Override
    public void run() {

        HomeActivity.this.runOnUiThread(new Runnable() {
            @Override
            public void run() {

                if (viewPager.getCurrentItem() == 0){
                    viewPager.setCurrentItem(1);
                }else if (viewPager.getCurrentItem() == 1){
                    viewPager.setCurrentItem(2);
                }else{

    }

    int id = item.getItemId();

    if (id == R.id.explore) {
        myMethod();
    }
    return false;

}

这是我的基本活动代码

import android.view.Menu;
import android.view.MenuInflater;

public class BaseActivity extends AppCompatActivity{
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.navigation_menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.explore:
            myMethod();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

public void myMethod(){
    Intent intent = new Intent(this,ExploreActivity.class);
    startActivity(intent);
}
public void exploreActivity(View view){
    myMethod();
}

public void packagesActivity(View view){
    Intent intent = new Intent(this,PackagesActivity.class);
    startActivity(intent);
}

public void dealsActivity(View view){
    Intent intent = new Intent(this,DealsActivity.class);
    startActivity(intent);
}
}

Answer 1

如果您在所有活动中都有相同的菜单，那么我将建议您创建一个菜单

然后将BaseActivity扩展到AppcompatActivity

使活动 1- >扩展BaseActivity

魔术来了->您不必一直使用setContentView。

使用一种XML使BaseActivity- > FrameLayout->使用

工具栏和框架布局

现在在Activity1中，在BaseActivity的 FrameLayout中扩展视图

并遵循相同的系统进行所有活动。

我有同样的情况->我必须在每个Activity中都显示sideMenu，所以最终得到了这个解决方案。

Answer 2

创建一个基本活动，在其中您为菜单项编写代码，然后将基本活动扩展到所有内部活动。

对于标题

创建一个通用的标题布局。

然后在您的HomeActivity中

abstract class HomeActivity extends Activity {
  protected TextView txtHeading;
  public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
  }


  protected void setHeading(int resId) {
     if(tv_title == null)
     txtHeading = findViewById(R.id.tv_title);
     if(tv_title != null)
       txtHeading.setText(resId);
  }
}

然后在其他活动中，例如activity_main.xml

主要活动

class MainActivity extends BaseActivity {
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      setHeading(R.string.heading_main);
   }
}

其他活动也一样

对于相同菜单选项

public class HomeActivity extends Activity {

    // other overidden methods

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.options_menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.item:
                // do what you want here
                return true;
            default:
               return super.onOptionsItemSelected(item);
        }
    }
}

然后在儿童活动中

  public class ChildActivity extends BaseActivity { 


    @Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    //getMenuInflater().inflate(R.menu.menu_second, menu);  <- remove this
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    return super.onOptionsItemSelected(item);
}
    }
