Android笔记-5-EditText密码和Checkbox二选一

EditText密码：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 　　　　　　 //设置为密文
11          MainActivity.this.password.setTransformationMethod(PasswordTransformationMethod.getInstance());
12
13      }
14
15   　　@Override
16      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  }

明文密文切换（Checkbox切换）：

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()){
                //设置为明文显示
                MainActivity.this.password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
            }
            else{
                //设置为密文显示
                MainActivity.this.password.setTransformationMethod(PasswordTransformationMethod.getInstance());
            }
        }
    }

}

Checkbox二选一

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);
　　　　}
　　}
}
