Android EditText值在intent中获取编辑后切屏会导致编辑信息无法保存的BUG

场景如当我在其他页面获取某个电话号码要跳转到拨号界面在拨号的EditText中显示该号码并编辑！此时编辑过程中出现锁屏解锁是编辑的数据不保存！

原因是我们获取Intent的数据时会在onResume中获取！

锁频后解锁时发出的Intent和之前跳转过来的是同一个！所以编辑数据不会保留会去INTENT中的数据！

解决方案一：

比较方便一点的！

在onPause中把Intent里的数据改变比如

Intent intent = getIntent();
String tel =mEditText.getText().toString();
Log.e("Dean", "onPause mEditText.getText()"+abc);
setIntent(intent.putExtra("tel", abc));

对应的Uri 的取值是一样的不过Uri可能需要重新NEW一个Intent而不是在原来的基础上改！

解决方案二：

GOOLGE源码里的解决方法：

直接贴代码了！

onCreate：
final Intent intent = getIntent();
intent.putExtra(EXTRA_IGNORE_STATE, true);
if (!resolveIntent() && icicle != null) {
            super.onRestoreInstanceState(icicle);
        }
onResume：
Activity parent = getParent();
// See if we were invoked with a DIAL intent. If we were, fill in the
// appropriate digits in the dialer field.
if (parent != null && parent instanceof DialtactsActivity) {
Uri dialUri = ((DialerPhoneActivity) parent).getAndClearDialUri();
if (dialUri != null) {
		resolveIntent();
		}
}

@Override
	protected void onNewIntent(Intent newIntent) {
		Log.i(TAG, "onNewIntent: intent=" + newIntent);
//		setIntent(newIntent);
		resolveIntent();
		setupDialUri(newIntent);
	}

	private void setupDialUri(Intent intent) {
        mDialUri = intent.getData();
    }

	/**
     * Retrieves the uri stored in {@link #setupDialUri(Intent)}. This uri
     * originally came from a dial intent received by this activity. The stored
     * uri will then be cleared after after this method returns.
     *
     * @return The stored uri
     */
    public Uri getAndClearDialUri() {
        Uri dialUri = mDialUri;
        mDialUri = null;
        return dialUri;
    }

	private boolean resolveIntent() {
		boolean ignoreState = false;

		// Find the proper intent
		final Intent intent;
		if (isChild()) {
			intent = getParent().getIntent();
			ignoreState = intent.getBooleanExtra(EXTRA_IGNORE_STATE, false);
		} else {
			intent = getIntent();
		}
		Log.i(TAG, "resolveIntent: intent=" + intent);
		// Resolve the intent
		final String action = intent.getAction();
		if (Intent.ACTION_DIAL.equals(action)
				|| Intent.ACTION_VIEW.equals(action)) {
			// see if we are "adding a call" from the InCallScreen; false by
			// default.
			Uri uri = intent.getData();
			if (uri != null) {
				if ("tel".equals(uri.getScheme())) {
					// Put the requested number into the input area
					String data = uri.getSchemeSpecificPart();
					mDigits.setText(data);
					mDigits.selectAll();
					mDigits.setBackgroundDrawable(mDigitsBackground);
				} else {
//                    String type = intent.getType();
//                    if (People.CONTENT_ITEM_TYPE.equals(type)
//                            || Phones.CONTENT_ITEM_TYPE.equals(type)) {
//                        // Query the phone number
//                        Cursor c = getContentResolver().query(intent.getData(),
//                                new String[] {PhonesColumns.NUMBER}, null, null, null);
//                        if (c != null) {
//                            if (c.moveToFirst()) {
//                                // Put the number into the input area
//                                setFormattedDigits(c.getString(0));
//                            }
//                            c.close();
//                        }
//                    }
				}
