通過Java 碼在編輯文本(EditText)旁邊放置圖標, setCompoundDrawablesWithIntrinsicBounds

通過 setCompoundDrawablesWithIntrinsicBounds() 方法可在編輯文本(EditText)旁邊放置圖標.

實例:

package com.AndroidEditText;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class AndroidEditTextActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        final EditText input = (EditText)findViewById(R.id.input);
        Button buttonClear = (Button)findViewById(R.id.clear);
        buttonClear.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    input.setText("");
   }});
        
        Drawable icon = getResources().getDrawable(R.drawable.icon);
        
        input.setCompoundDrawablesWithIntrinsicBounds(
          icon,  //left
          icon,  //top
          icon,  //right
          icon); //bottom

    }
}
