• 【Android Studio】Android实现跳转功能


    最近在玩Esp32,需要APP,顺带学了下这方面的东西。

    主要实现功能: 从主  mainActivity  跳转到otherActivity。

    新建一个hello工程,添加 otherActivity 和 otherxml.xml;

    mainActivity内容:

    package com.example.xiaoyehack.test;
    
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    
    import android.view.View;
    import android.content.Intent;
    
    public class MainActivity extends AppCompatActivity {
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
        }
    
        public void skip(View view){
            Intent intent = new Intent();
            intent.setClass(MainActivity.this,otherActivity.class);
            startActivity(intent);
        }
    }

    activity_main.xml

    <?xml version="1.0" encoding="utf-8"?>
    <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity">
    
        <Button
            android:id="@+id/button"
            android:layout_width="wrap_content"
            android:layout_height="79dp"
            android:layout_marginStart="148dp"
            android:layout_marginTop="32dp"
            android:layout_marginEnd="148dp"
            android:layout_marginBottom="276dp"
            android:onClick="skip"
            android:text="点击跳转"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/textView3" />
    
        <TextView
            android:id="@+id/textView3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="122dp"
            android:layout_marginTop="105dp"
            android:layout_marginEnd="122dp"
            android:layout_marginBottom="92dp"
            android:text="点击下面按钮实现跳转"
            app:layout_constraintBottom_toTopOf="@+id/button"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
    
    </android.support.constraint.ConstraintLayout>
    

      

    otherActivity内容:
    package com.example.xiaoyehack.test;
    
    import android.os.Bundle;
    import android.support.v7.app.AppCompatActivity;
    
    public class otherActivity extends AppCompatActivity {
    
        @Override
        protected void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.otherxml);
        }
    
    }
    

      otherxml内容:

    <?xml version="1.0" encoding="utf-8"?>
    <android.support.constraint.ConstraintLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    
        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="67dp"
            android:layout_marginStart="116dp"
            android:layout_marginTop="146dp"
            android:layout_marginEnd="100dp"
            android:layout_marginBottom="346dp"
            android:text="不要吹牛皮,就是一把梭!"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintVertical_bias="0.0" />
    </android.support.constraint.ConstraintLayout>
