我有 1 TextView& Buttonin 1 屏幕和ListView另一个屏幕，我想在按钮单击时将数据发送到列表视图。那么这怎么可能，是否有必要使用数据库或数组呢？以下是我制作的代码。
MainActivity.java
public class MainActivity extends Activity {
TextView tx ;
int tv;
int counter = 0;
String[] planets;
private ArrayList<String> mArray;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
planets = getResources().getStringArray(R.array.Jokes_array);
//final Button button = (Button) findViewById(R.id.button11);
tx = (TextView)findViewById(R.id.textViewapp1);
tx.setText(planets[counter]);
Button button = (Button)findViewById(R.id.btnsms);
Button btnFavr = (Button)findViewById(R.id.btnfav);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//startActivity(new Intent(IcontrolActivity.this,Settings.class));
/* Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
//String shareBody = (String) getText(R.id.textViewapp1);
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));*/
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.putExtra(Intent.EXTRA_TEXT, ((TextView) findViewById(R.id.textViewapp1)).getText());
sharingIntent.setType("text/plain");
startActivity(sharingIntent);
// TODO Auto-generated method stub
}
});
btnFavr.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast toast = Toast.makeText(MainActivity.this, R.string.messageWordAddedToFarvourite, Toast.LENGTH_SHORT);
toast.show();
/* SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();
editor.putString(tx,getString(R.id.textViewapp1));
editor.commit();*/
//ArrayList<String> arryList = new ArrayList<String>();
mArray.add(tx.getText().toString());
}
});
btnFavr.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
Intent intent = new Intent(getApplicationContext(), FavActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(intent);
return false;
}
});
}
还有另一个我正在处理的 Java 文件，它将在列表视图中显示内容，这些内容保存在点击事件中，长按它将显示 ListView 文件。
