我无法使用edittext在android textview项目中设置文本：
public class MainActivity extends Activity {
TextView textView1;
private Button button1;
private EditText editText1;
private Editable e;
private String ee;
private SharedPreferences sh1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView1 = (TextView) findViewById(R.id.textView1);
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
saveM1(editText1.getText().toString());
}
});
editText1.addTextChangedListener(eeeee);
sh1 = getSharedPreferences("sh1",MODE_PRIVATE);
}
private void saveM1(String save1){
SharedPreferences.Editor preferencesEditor = sh1.edit();
preferencesEditor.putString("save1",save1); //change this line to this
preferencesEditor.commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId())
{
case R.id.action_settings:
Intent i = new Intent(this,aa.class);
startActivity(i);
return true;
}
return true;
}
public TextWatcher eeeee = new TextWatcher(){
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
e = editText1.getText(); //eeee
textView1.setText("e"+e);
}
};
}
我的应用程序崩溃。请帮忙。
