直接上代码吧:

应用：

mPasswordFoundText.setOnClickListener(this);

ImageButton visibleBtn = (ImageButton) findViewById(R.id.psd_visible);visibleBtn.setOnClickListener(new PsdVisibleChangeListener(visibleBtn, mPasswordEdit));

PsdVisibleChangeListener方法：

public class PsdVisibleChangeListener implements View.OnClickListener {    private ImageButton imageButton;    private EditText editText;    public PsdVisibleChangeListener(ImageButton imageButton, EditText editText) {        this.editText = editText;        this.imageButton = imageButton;    }    @Override    public void onClick(View v) {        if (imageButton == null || editText == null) return;        if (imageButton.isSelected()) {            imageButton.setSelected(false);            editText.setTransformationMethod(PasswordTransformationMethod.getInstance());            editText.setSelection(editText.getText().length());        } else {            imageButton.setSelected(true);            editText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());            editText.setSelection(editText.getText().length());        }    }
