android界面布局之實現文本塊布局效果示例

復制代碼 代碼如下:
package cn.aibow.android.layoutdemo1;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MotionEvent;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

 private int[] idarr = new int[]{R.id.tv1,R.id.tv2,R.id.tv3,R.id.tv4,R.id.tv5,R.id.tv6,R.id.tv7,R.id.tv8};
 private int[] colorarr = new int[]{0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF,0xFFFFFFFF};
 private int[] bgarr = new int[]{0xFFFF6666,0xFF1e67c0,0xFFd47756,0xFF5a626f,0xFFee7434,0xFF3eadeb,0xFF0385fd,0xFF00a179};
 private String[] textarr = new String[]{"通訊電腦","生活廚衛","家用電器","日用百貨","母嬰玩具","戶外體育","汽車配件","其它商品"};

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  for(int i=0;i<idarr.length;i++){
   TextView tv = (TextView)findViewById(idarr[i]);
   tv.setText(textarr[i]);
   tv.setBackgroundColor(bgarr[i]);
   tv.setTextColor(colorarr[i]);
   tv.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
     TextView t = (TextView)v;
     showMessage("您點擊的是 : "+t.getText().toString());
    }
   });
  }
 }

 private void showMessage(String msg){
  Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }

}
