リストビューからsqlite（アンドロイドスタジオ）で他のアクティビティにjson情報を取得する方法

Question

だから何をしようとしているのですか？
HOMESCREEN --- newactivity ---> INTERNETSEARCHSCREEN ---- newactivity --- > EDITINGSCREEN

imはjsonを取得していますが、リストビューに表示されますが、今はリストビューから1つの映画を選択して映画名/年/夏/ imageurlを取得してEDITSCREENに表示します私はすべてのjsonのデータを取得し、私が望んでいた指定されたフィールドではありません....そしてhmmm私はSQLにそれを保存するか、編集画面で私のデータベースに追加する任意の意見は歓迎される場合：D

とEDITSCREEN：

public class EditMovie extends AppCompatActivity { 

EditText etMovieName ; 
EditText etMoviewSummery; 
EditText etURL ; 
Button btnsave; 
Button btnshow; 
Button btncancel; 
MovieDataSource mds; 
long id ; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_edit_movie); 


    //Instantiate DB query class 
    mds=new MovieDataSource(this); 
    //Run init method 
    init(); 

    //method to save/update customer to DB 
    btnsave.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      String moviename=etMovieName.getText().toString(); 
      String moviesummery=etMoviewSummery.getText().toString(); 
      String imageurl=etURL.getText().toString(); 

      //Instantiate , values from Intent 
      Movies newmovie=new Movies(moviename,moviesummery,imageurl,id); 
      mds.open(); 
      //will access the CustomerDataSource class to updateByRow method 
      mds.updateByRow(newmovie); 
      mds.close(); 
      //Transfering result to MainActivity 
      Intent i=new Intent(); 
      setResult(RESULT_OK,i); 
      finish(); 

     } 
    }); 

} 

public void init() 
{ 
    etMovieName=(EditText) findViewById(R.id.etMovieNameEDIT); 
    etMoviewSummery=(EditText) findViewById(R.id.etSummeryEDIT); 
    etURL=(EditText) findViewById(R.id.etURLEDIT); 

    btnsave=(Button) findViewById(R.id.btnsaveEDIT); 
    //btndelete=(Button) findViewById(R.id.updateBtnDelete); 
    // tvId=(TextView) findViewById(R.id.updatetvId); 

    //get the intent with the row id number & request code 
    id = getIntent().getLongExtra("rowId", 0); 
    //If DB row number is not 0 
    if(id!=0) { 
     //open DB connection 
     mds.open(); 
     //Instantiate and get the movie id from calling screen 
     Movies c = mds.getMovieById(id); 
     etMovieName.setText(c.getMovieName()); 
     etMoviewSummery.setText(c.getMovieSummery()); 
     etURL.setText(c.getImageURL()); 
     mds.close(); 
    } 
} 
} 

ああ、誰でも私はそれを検索するための二回Goボタンをクリックする必要がある理由のアイデアを持っている場合は？

と支援しよう/喜んで、誰のための感謝：D

Answer 1

は、あなたが実際にあなたが編集画面にオフに送信意思でそれを置くことができます。ちょうどあなたのオブジェクトが直列であることを確認してください

myObj = (MyObj) intent.getSerializableExtra("PUT_EXTRA_KEY"); 

：あなたの代わりにobjectを送信したい場合は

Intent intent = new Intent(this, EditMovie.class); 
intent.putExtra("json", myJson); 
startActivity(intent); 

は、その後、あなたのEditMovieのonCreate

Intent intent = getIntent(); 
String myJson = intent.getStringExtra("json"); 

に、それはより多くのようなものになるだろう。
