Android 布局最佳实践 之 使用自己的 ToolBar

源代码 传送门

效果图：

下面是 MainActivity.java

package com.nicerdata.mytoolbar;import android.content.Intent;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.Toolbar;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Toast;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Toolbar toolbar = (Toolbar) findViewById(R.id.id_toolBar);        assert toolbar != null;        // toolbar.setLogo(R.mipmap.ic_launcher);        // toolbar.setTitle("应用设置");        // toolbar.setSubtitle("Sub Title");        setSupportActionBar(toolbar);        // noinspection ConstantConditions        getSupportActionBar().setDisplayShowTitleEnabled(false);        // toolbar.setNavigationIcon(R.drawable.ic_arrow_back_white_18dp);        toolbar.setOnMenuItemClickListener(onMenuItemClick);    }    private Toolbar.OnMenuItemClickListener onMenuItemClick = new Toolbar.OnMenuItemClickListener() {        @Override        public boolean onMenuItemClick(MenuItem item) {            String msg = "";            switch (item.getItemId()) {                case R.id.action_edit:                    msg += "Click edit";                    break;                case R.id.action_share:                    msg += "Click share";                    break;                case R.id.action_settings:                    msg += "Click setting";                    break;            }            if (!msg.equals("")) {                showToast(msg);            }            return true;        }    };    private void showToast(String msg) {        Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.menu_main, menu);        return true;    }    public void toSecond(View view) {        startActivity(new Intent(this, SecondActivity.class));    }}

下面是 mytoolbar.xml，用于别的 layout 去 include

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="vertical">    <android.support.v7.widget.Toolbar        android:id="@+id/id_toolBar"        android:layout_width="match_parent"        android:layout_height="?attr/actionBarSize"        android:background="@color/HFColorPrimary"        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">        <TextView            android:id="@+id/id_title"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="这是标题"            android:textColor="@color/white"            android:textSize="16sp" />    </android.support.v7.widget.Toolbar></LinearLayout>

下面是另一个 Activiity.java

package com.nicerdata.mytoolbar;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.Toolbar;import android.view.View;import android.widget.TextView;public class SecondActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_second);        Toolbar toolbar = (Toolbar) findViewById(R.id.id_toolBar);        TextView title = (TextView) findViewById(R.id.id_title);        title.setText("用户反馈");        assert toolbar != null;        setSupportActionBar(toolbar);        //noinspection ConstantConditions        getSupportActionBar().setDisplayShowTitleEnabled(false);        toolbar.setNavigationIcon(R.drawable.ic_arrow_back_white_18dp);        toolbar.setNavigationOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                finish();            }        });    }}
