Question

为什么不在Click和TextView上显示menuItem。请任何人帮我显示我的menusItem。（我使用app：actionLayout =＆＃34; @ layout / login_icon_design＆＃34;）。当我们删除app：actionLayout标记时，菜单就会出现。

//dashboard.xml file

在这里输入代码

// login_icon_design.xml

<TextView
    android:id="@+id/qcId"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:paddingLeft="0dp"
    android:text="Active"
    android:textColor="@color/button_green"
    android:textSize="9dp" />

// DashboardActivity.java

  @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.

        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.dashboard, menu);
        final Menu m = menu;
        final MenuItem mitem = menu.findItem(R.id.button);
        TextView qcId= (TextView) mitem.getActionView().findViewById(R.id.qcId);
        SharedPreferences pref=this.getSharedPreferences("MyPref",MODE_PRIVATE);
        String refCode=pref.getString("refCode",null);
        qcId.setText(refCode);

        Intent intent = getIntent();
        String str2 = intent.getStringExtra("balance");
        menu.findItem(R.id.bal).setTitle("Avl. Bal. \u20B9" +str2);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();

        if(id == R.id.bal) {

        } else if(id == R.id.profile){
            Toast.makeText(this, "1", Toast.LENGTH_SHORT).show();

        } else if (id == R.id.logout){
            Toast.makeText(this, "2", Toast.LENGTH_SHORT).show();

        } else if(id == R.id.event) {
            Toast.makeText(this, "3", Toast.LENGTH_SHORT).show();

        } else if(id == R.id.history) {
            Toast.makeText(this, "4", Toast.LENGTH_SHORT).show();

        }
        return super.onOptionsItemSelected(item);
    }

你必须添加这几行

final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);

我在工具栏中有固定的图像和texview。现在它没有显示菜单
