我想创建一个简单的应用程序来上传我的位置。我有两个活动,在第一个活动中,用户可以输入参数 url 以使用编辑框上传,如果用户希望上传位置保存首选项按钮和开始按钮以获取位置活动,则为复选框.我尝试这个但没有工作...我如何调用我的函数启动和保存?任何帮助?调试时我有错误...点击按钮后
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SharedPreferences preferences = getSharedPreferences("gpstracker" , MODE_PRIVATE);
String strValue = preferences.getString("Url",strValued);
edittxtUrl = (EditText)findViewById(R.id.txtUrl);
edittxtUrl.setText(strValue);
Button buttonStart = (Button)findViewById(R.id.buttonStart);
buttonStart.setOnClickListener(startListener);
Button buttonSave = (Button)findViewById(R.id.buttonSave);
buttonSave.setOnClickListener(saveListener);
}
private OnClickListener startListener = new OnClickListener() {
public void onClick(View v) {
Start();
}
};
private OnClickListener saveListener = new OnClickListener() {
public void onClick(View v) {
Save();
}
};
public void Save() {
SharedPreferences preferences = getSharedPreferences("gpstracker" , MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
edittxtUrl = (EditText)findViewById(R.id.txtUrl);
String strUrl = edittxtUrl.getText().toString();
CheckBox chkTandC = (CheckBox)findViewById(R.id.chkTandC);
boolean blnTandC = chkTandC.isChecked();
editor.putString("Url", strUrl); // value to store
editor.putBoolean("TandC", blnTandC); // value to store
// Commit to storage
editor.commit();
}
public void Start() {
startActivity(new Intent(this, LocTracker.class));
}
