Android Toolbar 沉浸式使用

对于沉浸式的应用，网上有很多，我总结后写成两个基类，可以直接使用，说下注意的点有：1.用toolbar的activity主题要no actionbar;2.想要沉浸式的图片置顶需要Android5。0，这个代码要适配；3.更多的坑自己网上解决，培养下记录解决方法的习惯，最好自己写demo,例如文字居中，文字重叠。补充下：样式下colorPrimaryDark的颜色值是状态栏的，progressdialog圈圈的颜色值可以设置 android:indeterminateTint="@color/color_green"，配置更多的统一色调。

代码使用：

package jason.com.blankbardemo;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;

import jason.com.blankbardemo.ui.CollspingAty;
import jason.com.blankbardemo.ui.ImgTopAty;
import jason.com.blankbardemo.ui.ToolBarAty;
import jason.com.blankbardemo.ui.TransluBarAty;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void onClick_1(View view) {
        Intent intent = new Intent(this, ToolBarAty.class);
        startActivity(intent);
    }

    public void onClick_2(View view) {
        Intent intent = new Intent(this, ImgTopAty.class);
        startActivity(intent);

    }

    public void onClick_3(View view) {
        Intent intent = new Intent(this, TransluBarAty.class);
        startActivity(intent);
    }

    public void onClick_4(View view) {
        Intent intent = new Intent(this, CollspingAty.class);
        startActivity(intent);
    }
}

/ 直接继承基类就可以使用到toolbar

package jason.com.blankbardemo.ui;

import android.os.Bundle;

import jason.com.blankbardemo.R;
import jason.com.blankbardemo.base.BasebarAty;

//这个基类中我代码做了写死状态栏的高度=toolbar的padding,导致阴影会被toolbar的背景颜色覆盖掉
//我这么做，是避免在复杂的嵌套布局中留白，有时用fitwindow...=true,也是解决不了，例如CollapsingToolbarLayout
//如果想要阴影就继承baseimgAty就好
public class ToolBarAty extends BasebarAty {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tool_bar_aty);
        initAty();
    }

    private void initAty() {
        super.setBarTitle("带toolbar");
        super.showToolbar(true);    //默认为true
    }
}

//      true 设置状态栏透明
public class ImgTopAty extends BaseimgAty {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_img_top_aty);
    }
}

    ActionBar actionBar = getSupportActionBar();
    if (null != actionBar) {
        actionBar.setDisplayHomeAsUpEnabled(true);
        actionBar.setDisplayShowTitleEnabled(false);
    }
    this.mAppBarLayout.setBackgroundResource(R.drawable.bgpic);

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:

//大家的Androidstudio版本可能都不同，这里下载解压后不要着急打开项目，打开项目文件夹修改几个文件可以使用你本地的gradle版本，打开你原来运行过的项目替换以下代码：
1.打开项目的build.gradle文件 ，修改替换成你原有的项目代码语句，保存文件。
//classpath ‘com.android.tools.build:gradle:2.2.2’
2.打开项目gradle/warpper/gradle-wrapper.properties文件,替换保存：
//distributionUrl=https://services.gradle.org/distributions/gradle-2.14.1-all.zip
3.打开项目app/build.gradle，修改以下工具版本,打开你原来运行过的项目替换以下代码：
//compileSdkVersion 25
//buildToolsVersion “25.0.3”
//compile ‘com.android.support:appcompat-v7:25.3.1’
//compile ‘com.android.support:design:25.3.1’
