EditText密碼：明文和密文

密文：

 1 public class MainActivity extends Activity { 2        3       private EditText password = null; 4       @Override 5       protected void onCreate(Bundle savedInstanceState) { 6           super.onCreate(savedInstanceState); 7           setContentView(R.layout.activity_main); 8            9          this.password = (EditText) super.findViewById(R.id.pwdEdittext);10 　　　　　　 //設定為密文11          MainActivity.this.password.setTransformationMethod(PasswordTransformationMethod.getInstance()); 12         13      }14  15   　　@Override16      public boolean onCreateOptionsMenu(Menu menu) {17          // Inflate the menu; this adds items to the action bar if it is present.18          getMenuInflater().inflate(R.menu.main, menu);19          return true;20      }21  }

明文密文切換（Checkbox切換）：

public class MainActivity extends Activity {        private EditText password = null;    private CheckBox show = null;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                this.password = (EditText) super.findViewById(R.id.pwdEdittext);        MainActivity.this.password.setTransformationMethod(PasswordTransformationMethod.getInstance());        this.show = (CheckBox) super.findViewById(R.id.display_checkBox);        this.show.setOnClickListener(new OnclickListenerlmp());    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }    public void register(View view){                Intent intent = new Intent();        intent.setClass(this, RegisterActivity.class);        this.startActivity(intent);            }    private class OnclickListenerlmp implements OnClickListener{        @Override        public void onClick(View v) {            // TODO Auto-generated method stub            if(MainActivity.this.show.isChecked()){                //設定為明文顯示                MainActivity.this.password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());            }            else{                //設定為密文顯示                MainActivity.this.password.setTransformationMethod(PasswordTransformationMethod.getInstance());            }        }    }}

Checkbox二選一

public class RegisterActivity extends Activity {　　private CheckBox choose1 = null;　　private CheckBox choose2 = null;　　@Override　　protected void onCreate(Bundle savedInstanceState) {　　　　super.onCreate(savedInstanceState);　　　　setContentView(R.layout.activity_register);　　this.choose1 = (CheckBox) super.findViewById(R.id.sex_checkBox1);　　this.choose2 = (CheckBox) super.findViewById(R.id.sex_checkBox2);　　}　　@Override　　public boolean onCreateOptionsMenu(Menu menu) {　　　　// Inflate the menu; this adds items to the action bar if it is present.　　　　getMenuInflater().inflate(R.menu.register, menu);　　　　return true;　　}　　public void choose(View view){　　　　if(RegisterActivity.this.choose1.isChecked()){　　　　choose2.setChecked(false);　　　}　　　　else{　　　　　　choose1.setChecked(false);　　　　}　　}}
