android > EditText 控件操作

* EditText自动换行

<EditText     android:layout_width="0dip"    android:layout_height="120dip"    android:layout_margin="10dip"      android:scrollbars="vertical"    android:scrollbarAlwaysDrawVerticalTrack="true"    android:gravity="top"    android:inputType="textCapSentences|textMultiLine"    android:textColor="#000000"     />

* EditText 密码显示/隐藏

if(pass_show.isChecked()){//显示明文pass.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);}else{//显示密码pass.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);}

* 监听EditText 发生变化

    public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.main);                    text = (EditText)findViewById(R.id.text);          text.addTextChangedListener(textWatcher);      }            private TextWatcher textWatcher = new TextWatcher() {                    @Override            public void afterTextChanged(Editable s) {                 // TODO Auto-generated method stub                 Log.d("TAG","afterTextChanged--------------->");           }                     @Override         public void beforeTextChanged(CharSequence s, int start, int count,                  int after) {              // TODO Auto-generated method stub              Log.d("TAG","beforeTextChanged--------------->");          }            @Override            public void onTextChanged(CharSequence s, int start, int before,                     int count) {                 Log.d("TAG","onTextChanged--------------->");                str = text.getText().toString();              try {                  //if ((heighText.getText().toString())!=null)                   Integer.parseInt(str);                                } catch (Exception e) {                  // TODO: handle exception                  showDialog();              }                                        }                        };

*默认不获取焦点

在EditText父级加属性

android:focusable="true"   android:focusableInTouchMode="true"
