獲取錯誤“無法對類型為Intent的非靜態方法putExtra（String，String）進行靜態引用”

Question

我試圖從我的第一個屏幕中的EditText獲取數據，然后能夠在我的第二個屏幕中使用它。 我正在使用putExtra方法但它不斷給我錯誤消息

無法從Intent類型對非靜態方法putExtra（String，String）進行靜態引用

有誰知道如何解決這個問題？ 謝謝！！！

final EditText et = (EditText) findViewById(R.id.word);

    Button btn1 = (Button) findViewById(R.id.go_btn2);
    btn1.setOnClickListener(new OnClickListener(){
        MediaPlayer buttonSound = MediaPlayer.create(MainActivity.this, R.raw.button_click);
        @Override
        public void onClick(View v){
            buttonSound.start();
            startActivity(new Intent(MainActivity.this, Second.class));
            Intent.putExtra("name", et.getText().toString());
        }});

Answer 1

您需要先創建一個Intent對象：

final EditText et = (EditText) findViewById(R.id.word);

    Button btn1 = (Button) findViewById(R.id.go_btn2);
    btn1.setOnClickListener(new OnClickListener(){
        MediaPlayer buttonSound = MediaPlayer.create(MainActivity.this, R.raw.button_click);
        @Override
        public void onClick(View v){
            buttonSound.start();
            Intent intent = new Intent(MainActivity.this, Second.class);
            intent.putExtra("name", et.getText().toString());
            startActivity(intent);
        }});

Answer 2

您必須創建Intent類的實例然后才能使用

final EditText et = (EditText) findViewById(R.id.word);

    Button btn1 = (Button) findViewById(R.id.go_btn2);
    btn1.setOnClickListener(new OnClickListener(){
        MediaPlayer buttonSound = MediaPlayer.create(MainActivity.this, R.raw.button_click);
        @Override
           public void onClick(View v){
           buttonSound.start();
           Intent intent = new Intent(MainActivity.this, Second.class) ;          
           intent.putExtra("name", et.getText().toString());
           startActivity(intent);
        }});

Answer 3

final EditText et = (EditText) findViewById(R.id.word);

Button btn1 = (Button) findViewById(R.id.go_btn2);
btn1.setOnClickListener(new OnClickListener(){
    MediaPlayer buttonSound = MediaPlayer.create(MainActivity.this, R.raw.button_click);
    @Override
    public void onClick(View v){
        buttonSound.start();
       Intent intent = new Intent(MainActivity.this, Second.class)
        startActivity(intent);
       intent..putExtra("name", et.getText().toString());
        //Intent.putExtra("name", et.getText().toString());//**This cause problem in your code**
    }});
