问题描述
我是移动开发的新手，我仍然很难适应环境，我试图使用 viewpager 在三个 TableLayouts 之间移动，但我无法工作。
代码布局.XML：
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"> <!-- esto permitira que el ocupe toda la pantalla el -->
<TableLayout
android:id="@+id/mi_tabla_layout"
android:layout_width="wrap_content"
android:layout_height="match_parent"/>
</HorizontalScrollView>
</ScrollView>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"> <!-- esto permitira que el ocupe toda la pantalla el -->
<TableLayout
android:id="@+id/mi_tabla_layout1"
android:layout_width="wrap_content"
android:layout_height="match_parent"/>
</HorizontalScrollView>
</ScrollView>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"> <!-- esto permitira que el ocupe toda la pantalla el -->
<TableLayout
android:id="@+id/mi_tabla_layout2"
android:layout_width="wrap_content"
android:layout_height="match_parent"/>
</HorizontalScrollView>
</ScrollView>
<ImageView android:id="@+id/pagerImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerInside"/>
</LinearLayout>
这将是 MAIN，根据教程，我设法创建了三个表 代码：MainActivity
package com.example.tabla_test;
import androidx.appcompat.app.AppCompatActivity;
import androidx.viewpager.widget.ViewPager;
import android.content.*;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Adapter;
import android.widget.TableLayout;
import android.widget.*;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
TableLayout tabla,tabla1,tabla2;
EditText nombre,apellido;
String[] header={"Id","Nombre","Apellido"};
String[] header1={"Id1","Nombre1","Apellido1"};
String[] header2={"Id2","Nombre2","Apellido2"};
ArrayList<String[]> filas=new ArrayList<>();
ArrayList<String[]> filas1=new ArrayList<>();
ArrayList<String[]> filas2=new ArrayList<>();
TableDynamic tablaDinamica,tablaDinamica1,tablaDinamica2 ;
ViewPager ViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/*nombre=findViewById(R.id.txtName);
apellido=findViewById(R.id.txtLastName);*/
tabla=findViewById(R.id.mi_tabla_layout);
tabla1=findViewById(R.id.mi_tabla_layout1);
tabla2=findViewById(R.id.mi_tabla_layout2);
tablaDinamica=new TableDynamic(tabla,getApplicationContext());
tablaDinamica1=new TableDynamic(tabla1,getApplicationContext());
tablaDinamica2=new TableDynamic(tabla2,getApplicationContext());
tablaDinamica.addHeader(header);
tablaDinamica.addData(getClientes());
tablaDinamica1.addHeader(header1);
tablaDinamica1.addData(getClientes1());
tablaDinamica2.addHeader(header2);
tablaDinamica2.addData(getClientes2());
tablaDinamica.backgroundHeader(Color.GRAY);
tablaDinamica1.backgroundHeader(Color.GRAY);
tablaDinamica2.backgroundHeader(Color.GRAY);
}
private ArrayList<String[]> getClientes(){
filas.add(new String[]{"1","Pedro","Lopez"});
filas.add(new String[]{"2","Juan","Villa"});
filas.add(new String[]{"3","Aldo","Torres"});
filas.add(new String[]{"4","Fiorella","Canto"});
return filas;
/* Adapter = clientadapter(filas,this@MainActivity)
ViewPager.Adapter = Adapter;*/
}
private ArrayList<String[]> getClientes1(){
filas1.add(new String[]{"1","xd","Lopez"});
filas1.add(new String[]{"2","xdd","Villa"});
filas1.add(new String[]{"3","xddd","Torres"});
filas1.add(new String[]{"4","xdddd","Canto"});
return filas1;
}
private ArrayList<String[]> getClientes2(){
filas2.add(new String[]{"1","V:","Lopez"});
filas2.add(new String[]{"2","Villa"});
filas2.add(new String[]{"3","Torres"});
filas2.add(new String[]{"4","Canto"});
return filas2;
}
}
我已经使用了教程和文档，但我仍然没有实现我的目标，即能够使用 viewpager 在对话框中创建的三个表之间导航，使用尽可能多的本机代码而无需导入外部库
这将是我的最终目标
