android连续多个界面跳转与回退的实现

新建一个module

选择第一个phone&Table Module

起个名字

选择Empty Activity，接下来finish即可

目录结构：

 右键单击module新建三个Activity分别是MainActivity,NextActivity,ThirdActivity

得到三个***ACtivity.java,自动生成3个对应的activity_***.xml,并且在AndroidManifest.xml中得到如下对新的界面注册登记的代码：

 MainActivity.java

public class MainActivity extends AppCompatActivity {
    Button btnNext;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnNext = (Button) findViewById(R.id.button);
        btnNext.setonClickListener(
                new View.onClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent=new Intent(getApplicationContext(),NextActivity.class);
                        startActivity(intent);
                    }
                }
        );
    }
}

NextActivity.java

public class NextActivity extends AppCompatActivity {
    Button btnBack, btnGoToThirdPage;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_next);
        btnBack = (Button) findViewById(R.id.btnBack);
        btnGoToThirdPage = (Button) findViewById(R.id.btnGoToThirdPage);
        btnBack.setonClickListener(
                new View.onClickListener() {
                    @Override
                    public void onClick(View v) {
//                        返回到上一个界面
                        finish();
                    }
                }
        );
        btnGoToThirdPage.setonClickListener(
                new View.onClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent intent = new Intent(getApplicationContext(), ThirdActivity.class);
                        startActivity(intent);
                    }
                }
        );
    }
}

ThirdActivity.java

public class ThirdActivity extends AppCompatActivity {
    Button btnThirdBack;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_third);
        btnThirdBack=(Button)findViewById(R.id.btnThirdBack);
        btnThirdBack.setonClickListener(
                new View.onClickListener() {
                    @Override
                    public void onClick(View v) {
                        finish();
                    }
                }
        );
    }
}

 activity_main.xml

activity_next.xml

activity_third.xml

实现左上角回退箭头，只需在AndroidManifest.xml进行如下修改

运行结果是
