主界面布局activity_main.xml

  1. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" >
  3.     <Button android:id="@+id/btn_main_test1" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="测试常用简单的Component" />
  5.     <Button android:id="@+id/btn_main_test2" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="测试菜单Component" />
  7.     <Button android:id="@+id/btn_main_test3" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="测试进度条Component" />
  9.     <Button android:id="@+id/btn_main_test4" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="测试对话框Component" />
  11. </LinearLayout>

点不同的按钮，启动不同的Activity

  1. package com.example.uidemo;
  3. import android.app.Activity;
  4. import android.content.Intent;
  5. import android.os.Bundle;
  6. import android.view.View;
  7. import android.view.View.OnClickListener;
  9. public class MainActivity extends Activity implements OnClickListener { 
  11.     @Override
  12.     protected void onCreate(Bundle savedInstanceState) { 
  13.         super.onCreate(savedInstanceState);
  14.         setContentView(R.layout.activity_main);
  15.         findViewById(R.id.btn_main_test1).setOnClickListener(this);
  16.         findViewById(R.id.btn_main_test2).setOnClickListener(this);
  17.         findViewById(R.id.btn_main_test3).setOnClickListener(this);
  18.         findViewById(R.id.btn_main_test4).setOnClickListener(this);
  19.     }
  21.     @Override
  22.     public void onClick(View v) { 
  23.         switch (v.getId()) { 
  24.         case R.id.btn_main_test1:
  25.             startActivity(new Intent(this, SimpleActivity.class));
  26.             break;
  27.         case R.id.btn_main_test2:
  28.             startActivity(new Intent(this, MenuActivity.class));
  29.             break;
  30.         case R.id.btn_main_test3:
  31.             startActivity(new Intent(this, ProgressActivity.class));
  32.             break;
  33.         case R.id.btn_main_test4:
  34.             startActivity(new Intent(this, DialogActivity.class));
  35.             break;
  37.         default:
  38.             break;
  39.         }
  41.     }
  42. }
