工具栏按钮单击事件功能 [英] Toolbar button click event functionality

问题描述

我已经在工具栏中创建了设置按钮，现在，每当我单击设置按钮时，都需要将屏幕导航到设置屏幕.

I have created settings button in Toolbar, now I need to navigate the screen to settings screen, when ever i click the settings button.

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="schemas.android.com/apk/res/android"; xmlns:app="schemas.android.com/apk/res-auto">;
 <item android:id="@+id/action_settings" 
android:title="ConfigApp" 
android:icon="@drawable/ic_action_name" 
app:showAsAction="ifRoom" /> 
</menu>

推荐答案

您应该覆盖 onCreateOptionsMenu 和 onOptionsItemSelected 方法，并采用特定的 id 从菜单项中导航到设置屏幕.

you should override the onCreateOptionsMenu and onOptionsItemSelected methods and take that particular id from menuitem and navigate to settings screen.

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.your_menu_xml, menu);
        return true;
    }

@Override
 public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()){
            case R.id.action_settings:
                Intent i = new Intent(yourActivity.this, SettingsActivity.class)
                startActivity(i);
                break;
            default:
                return super.onOptionsItemSelected(item);
        }
        return super.onOptionsItemSelected(item);
    }
