MainAcitivty简单使用
import android.os.Bundle; import android.support.v7.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final CNToolbar toolbar = (CNToolbar) findViewById(R.id.toolbar); toolbar.setOnLeftButtonClickListener(new CNToolbar.OnLeftButtonClickListener() { @Override public void onClick() { finish(); } }); toolbar.setOnRightButtonClickListener(new CNToolbar.OnRightButtonClickListener() { @Override public void onClick() { toolbar.setShowSearchView(); } }); } }

Values下创建atts.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="CNToolbar"> <attr name="showSearchView" format="boolean"/> <attr name="leftButtonIcon" format="reference"/> <attr name="rightButtonIcon" format="reference"/> <attr name="myTitle" format="string"/> </declare-styleable> </resources>
style.xml
<resources> <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <item name="colorPrimary">@color/red</item> <item name="colorPrimaryDark">@color/green</item> <item name="colorAccent">@color/blue</item> <item name="android:textColorPrimary">@color/white</item> <item name="android:windowActionBar">false</item> <item name="android:windowNoTitle">true</item> <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item> </style> </resources>
