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);
}
}
