droid 设置控件百分比宽度

 

思路:先获取屏幕的宽度,然后根据屏幕的宽度设置控件的宽度.高度同理

package name.liux.activity;

import android.app.Activity;
import android.os.Bundle;
import android.view.Display;
import android.widget.EditText;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;

public class Test extends Activity {
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  Display display = this.getWindowManager().getDefaultDisplay();
  int width = display.getWidth();
  TableLayout tab = new TableLayout(this);
  for(int i =0;i<10;i++){
   TableRow tr = new TableRow(this);
   TextView tv = new TextView(this);
   tv.setText("ssss"+i);
   tv.setWidth((int) ((width)*0.3));
   EditText et = new EditText(this);
   et.setWidth((int) ((width)*0.7));
   tr.addView(tv);
   tr.addView(et);
   tab.addView(tr);
  }
  setContentView(tab);
 }
}
