Question

我已经尝试过：

EditText edText1 = (EditText) findViewById(R.id.editText1);
String str = edText1.getText().toString();

我只获得数字而不是字符。如何获取EditText文本以便将其放在字符串上并对其进行操作？

Answer 1

// first set the Input type of the EditText in the Java class like this;

EditText edText1 = (EditText) findViewById(R.id.editText1);

edText1.setInputType(InputType.TYPE_CLASS_TEXT);

String str = edText1.getText().toString();

这就是我项目中按钮的外观

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        createLog("Called method onCreate");

    Button addTextButton = (Button) findViewById(R.id.button);

    final EditText vEditText = (EditText) findViewById(R.id.editText);

    addTextButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String enteredText = vEditText.getText().toString();

            if (enteredText.length() > 0){
                String existingText =((TextView) findViewById(R.id.textView)).getText().toString();
                ((TextView) findViewById(R.id.textView)).setText(existingText + (char)10 + (char)13 + enteredText );
                vEditText.setText("");
            }
        }
    });

创建获取方法

    editText = findViewById(R.id.editText);
    String s = getString(editText.getText().toString()


    public String getString(String text){
       return text;
    }

如何将EditText的内容保存到String中？ Android的
