我需要应用程序传递与其关联的一些字符串值，以便在用户单击图像时立即传递到文本中。如何使用android中的单击侦听器来实现以下任务。没有必要填写我给出的代码片段。欢迎任何关于设计的新想法。

Answer 1

您可以将文本设置为Tag到图像，以便您可以获取该文本onClick事件。 Tag可以用XML或动态设置。

public class TrialActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ImageView img = (ImageView)findViewById(R.id.imageView1);
        img.setTag("YOur text");
        img.setClickable(true);
        img.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
                   String urText= arg0.getTag().toString(); 
                   EditText edt = (EditText)findViewById(R.id.editText1);
                   edt.setText(urText);
        }
      });      
    }
}

此代码演示了如何动态实现您的需求。
